Windows 98 - Qcow2

Running Windows 98 in a modern virtual environment typically requires the QEMU emulator, which uses the QCOW2 (QEMU Copy-On-Write) disk format. This format is efficient because it only grows as data is added to the virtual disk. 1. Preparing the Virtual Hard Disk

You first need to create a blank virtual disk image using the qemu-img tool. Command: qemu-img create -f qcow2 win98.qcow2 4G

Size Note: A 4GB to 8GB disk is standard. While 600MB is technically enough for a base install, larger images allow room for software and games. 2. Recommended QEMU Launch Settings

Windows 98 is sensitive to modern hardware speeds and features. Use these specific flags for the best stability:

CPU & RAM: Emulating a pentium3 with 256MB or 512MB of RAM is the "sweet spot." Allocating more than 512MB can cause the OS to crash or fail to boot.

Graphics: Use -vga cirrus or -vga std for basic compatibility.

Audio: The -device sb16 (Sound Blaster 16) is the most compatible audio hardware for this era.

Example Installation Command:qemu-system-i386 -cpu pentium3 -m 256 -hda win98.qcow2 -cdrom win98se.iso -boot d -soundhw sb16 -vga std 3. Essential Post-Installation Fixes

Windows 98 "out of the box" will have limited resolution and may run slowly.

32-bit Color & High Res: Install the VBEMP (Universal VESA) or SoftGPU drivers to unlock 1024x768 resolution and 32-bit color.

Stability Patches: Use projects like the Windows 98 QuickInstall or unofficial Service Pack 3 to fix common QEMU-related hangs and crashes.

Networking: If the default network card isn't found, try forcing an ISA model with -net nic,model=ne2k_isa. 4. Where to Find Pre-Configured Images

If you prefer not to install from scratch, several communities provide pre-made QCOW2 or VM images: installing windows 98, windows xp, and starcraft in qemu

The Legacy Trap

The email from the client was short and panicked: "We have a legal hold on the design files for the 1998 Metro interface. The only machine that can read the proprietary format crashed. If we don't open these .prs files by tomorrow, we lose the case."

I called the client immediately. "What kind of machine are we talking about?"

"A custom workstation," the client said. "It ran Windows 98. The hard drive is making a clicking noise. It’s dead."

I rubbed my temples. Finding a replacement hard drive for a 25-year-old proprietary workstation was possible, but not in 24 hours. Installing Windows 98 on modern hardware was a nightmare of driver incompatibilities and BIOS settings.

"Send me the drive," I said. "But I’m not fixing the hardware. I’m moving your house to a new neighborhood."

The Setup

Three hours later, a courier handed me a heavy, dusty tower. I didn't bother plugging in a monitor or keyboard. I popped the side panel, removed the failing IDE drive, and hooked it up to a USB-to-IDE adapter. My Linux workstation recognized it immediately, though the partition table was badly damaged.

I wasn't going to repair the file system on the metal. That was too risky. I needed a pristine environment.

I opened a terminal. I didn't reach for a Windows 10 ISO. I needed the specific environment the software was built for. I needed Windows 98.

The Command

I typed the search query into my browser: windows 98 qcow2.

For a sysadmin, this specific search string is a lifeline. It bypasses the need to hunt down a physical CD-ROM, rip it, and convert it. It looks for a pre-configured, copy-on-write disk image format (qcow2) used by QEMU and KVM. Ideally, I was looking for a ready-made image that had the OS installed, saving me an hour of installation time.

I found a trusted archive containing Win98.qcow2. I downloaded it and placed it in my working directory.

Now came the surgery. I wasn't going to use that fresh image as my primary drive; I was going to use it as the "donor" for the operating system.

I created a new, larger disk image to house the system and the recovered data: qemu-img create -f qcow2 recovery_drive.qcow2 10G

Then, I cloned the fresh Windows 98 install onto the new drive: qemu-img dd if=Win98.qcow2 of=recovery_drive.qcow2

Finally, I needed to attach the client's failing drive as a secondary drive. I used ddrescue to image the physical drive into a raw image file first, to minimize stress on the dying hardware, then converted that raw image to qcow2 format.

qemu-img convert -O qcow2 failing_drive.raw failing_drive.qcow2

The Boot

I launched the virtual machine.

qemu-system-i386 -m 512 -hda recovery_drive.qcow2 -hdb failing_drive.qcow2 -enable-kvm

The window popped up. The familiar BIOS POST text scrolled by, followed by the iconic Windows 98 splash screen.

I held my breath. Windows 98 was notoriously finicky about hardware changes. Moving from a custom 1998 workstation to a virtualized Intel Icelake architecture could trigger a blue screen instantly.

The desktop loaded. It was a clean, default Windows 98 desktop.

I double-clicked My Computer.

Drive C: was the fresh Windows install. Drive D: was the client's old drive.

I navigated to D:\Projects\Metro. The folder opened instantly. The proprietary .prs files were there. The file system corruption that prevented the old hardware from booting hadn't affected the actual user data.

The Export

The files were visible, but I couldn't just drag and drop them to my Linux host because Windows 98 doesn't understand modern network protocols or USB mass storage easily.

I had a trick up my sleeve. I shut down the VM and mounted the qcow2 image directly on my Linux host using guestmount.

guestmount -a recovery_drive.qcow2 -m /dev/sda1 /mnt/vm

I copied the files from the mounted image to a shared network folder. The client received the files twenty minutes later.

The Aftermath

The client asked, "Can you send back the working computer?"

"It never left," I replied. "You have the files. The computer is a 20MB file on my server called windows 98 qcow2."

Why Windows 98 on modern hardware?

Retro gaming (DOS + Win9x era)
Legacy hardware/software testing
Preserving old projects

Shared folder (via network)

Set up SMB share on host
Use net use e: \\host\share in Win98

Step 5: Optimize the QCOW2 Image

After installing Windows 98 and configuring the virtual machine, you can optimize the QCOW2 image by:

Removing unnecessary files and programs
Defragmenting the disk
Running disk cleanup and virus scans

Tips and Tricks

Here are some additional tips and tricks to keep in mind:

Use a compatible graphics card: Windows 98 may not support modern graphics cards, so consider using a virtual graphics card like Cirrus VGA or S3 Trio32.
Configure sound: Sound Blaster 16 or other compatible sound cards can enhance the audio experience in Windows 98.
Use virtual networking: You can configure virtual networking to allow your Windows 98 VM to access the internet or local network.
Keep it clean: Regularly clean up temporary files and perform disk maintenance to keep your QCOW2 image running smoothly.

Conclusion

Creating a Windows 98 QCOW2 image is a fun and educational project that allows you to relive the nostalgia of old-school computing. By following these steps, you can create a fully functional Windows 98 virtual machine that can run on modern hardware. Whether you're a retrocomputing enthusiast, a researcher, or simply someone looking for a fun project, creating a Windows 98 QCOW2 image is a great way to experience the best of old-school computing.

Additional Resources

If you're interested in learning more about Windows 98, QCOW2 images, or virtualization, here are some additional resources:

QEMU documentation: The official QEMU documentation provides detailed information on creating and managing QCOW2 images.
Windows 98 documentation: Microsoft provides archived documentation for Windows 98, including installation guides and technical notes.
Retrocomputing communities: Join online communities, forums, or social media groups dedicated to retrocomputing to connect with other enthusiasts and learn more about old-school computing.

To run Windows 98 using a QCOW2 image in QEMU, you need to create a virtual hard disk and then boot from an installation ISO. Windows 98 typically requires a legacy machine type and specific emulated hardware to work correctly. 1. Create the QCOW2 Disk Image

First, generate a virtual hard drive. A size between 512 MB and 2 GB is standard. Windows 98 may have issues with disks larger than 2 GB unless you specifically enable large disk support during the FDISK process. qemu-img create -f qcow2 win98.qcow2 2G Use code with caution. Copied to clipboard 2. Launch the Installation

Use qemu-system-i386 to start the VM. You should use the i440fx (pc) machine type rather than the modern Q35, as it has better legacy support. Recommended Command:

qemu-system-i386 -m 256 -cpu pentium3 -M pc -hda win98.qcow2 \ -cdrom win98se.iso -boot d -vga cirrus -soundhw sb16 \ -net nic,model=pcnet -net user -display sdl Use code with caution. Copied to clipboard 3. Essential VM Settings

To ensure a stable experience, keep these configurations in mind:

Memory (-m): 128 MB to 256 MB is the "sweet spot". Going above 512 MB can cause Windows 9x to crash or fail to boot without manual patches.

CPU (-cpu): Emulating a pentium2 or pentium3 provides the best compatibility.

Graphics (-vga): The cirrus driver is natively supported by Windows 98. For higher resolutions and 32-bit color later, consider using SoftGPU.

Sound (-soundhw): Use sb16 (Sound Blaster 16) for the most reliable audio.

Mouse: To fix "sticky" mouse issues, add -device usb-tablet if your host supports it, though you may need a USB driver for Windows 98 to make it work. 4. Post-Installation Drivers

After the initial Windows setup, you will likely need extra drivers for modern performance:

Video: Install the Universal VESA or SoftGPU driver for better resolutions.

Network: The pcnet or ne2k_pci models usually work out of the box with the drivers included on the Windows 98 CD.

KVM: If you are on a Linux host, adding -enable-kvm significantly speeds up the VM, but it can sometimes cause stability issues with Windows 9x.

To set up or run Windows 98 using a QCOW2 disk image (the native format for QEMU), you can either create a fresh image and install it from an ISO or download pre-configured images from community repositories. 1. Creating a Windows 98 QCOW2 Image

To create a virtual hard drive for a new installation, use the qemu-img tool. Windows 98 supports up to 137 GB, but smaller sizes (e.g., 2 GB to 4 GB) are safer for stability.

Command to create disk:qemu-img create -f qcow2 win98.qcow2 2G 2. Recommended Installation Settings

Windows 98 is highly sensitive to modern hardware emulation. Using the following flags in QEMU ensures the best compatibility: CPU: Use pentium or pentium2 for best results.

Memory: Limit RAM to 256MB or 512MB. Windows 98 often crashes if given more than 1GB of RAM.

Video: The cirrus VGA driver is the most compatible "out-of-the-box". For 32-bit color and higher resolutions, community drivers like SoftGPU are recommended.

Example Launch Command:qemu-system-i386 -m 256 -cpu pentium2 -hda win98.qcow2 -cdrom win98se.iso -boot d -vga cirrus -net nic,model=pcnet -net user 3. Resources & Downloads QEMU config for Windows 98 that will work with v86? #945

To get a Windows 98 environment running in the format, you generally have two paths: creating your own image from an ISO (the most stable method) or finding a pre-built one. 1. Create Your Own QCOW2 Image

This is recommended because pre-made images can be buggy or contain unwanted configurations. You can use to build one yourself. Create the Disk : Open your terminal or command prompt and run: qemu-img create -f qcow2 windows98.qcow2 2G Launch the Installer

: Use a Windows 98 ISO to boot the VM and install it onto your new QCOW2 disk:

To create a Windows 98 environment using a qcow2 disk image, you'll primarily use QEMU, an open-source emulator. The qcow2 format is QEMU's native "Copy on Write" format, which is efficient because it only grows in size as you add data to the virtual disk. 1. Create the qcow2 Disk Image

First, you need to generate the virtual hard drive file. A size of 1GB to 4GB is usually perfect for Windows 98.

Open your terminal or command prompt and run:qemu-img create -f qcow2 win98.qcow2 2G 2. Boot and Install Windows 98

You will need a Windows 98 SE (Second Edition) ISO file. To begin the installation, use a command similar to the one below to launch the VM and boot from the "CD-ROM":

qemu-system-i386 -m 256 -hda win98.qcow2 -cdrom win98se.iso -boot d -cpu pentium3 -vga cirrus -net nic,model=pcnet -net user Key Configuration Tips:

Memory (-m): Set this between 128MB and 256MB. Going over 512MB often causes Windows 98 to crash during boot.

VGA (-vga): Using cirrus is highly compatible with the default drivers in Windows 98.

Sound (-soundhw): Use sb16 (Sound Blaster 16) for the best chance of audio working immediately. 3. The Installation Steps Once the VM starts, follow these classic setup steps: QEMU config for Windows 98 that will work with v86? #945

Here’s a sample review for a Windows 98 QCOW2 image (typically used with QEMU/KVM).
I’ve written it from the perspective of a retro computing enthusiast or developer testing legacy software.

Title: Nostalgic and surprisingly usable – but expect to tinker

Rating: ⭐⭐⭐⭐☆ (4/5)

I downloaded the pre-built Windows 98 SE QCOW2 image to run under QEMU on a Linux host. Here’s my honest take after a few days of testing.

Pros:

Plug and play (mostly): The image booted immediately with qemu-system-x86_64 -hda win98.qcow2 -m 256. No installation wait.
Pre-configured drivers: Sound (SB16), network (Realtek RTL8029), and VESA framebuffer worked out of the box. Even mouse integration (via usb-tablet) was easy to enable.
Stable enough: With QEMU’s softmmu and kvm disabled (or using -cpu host,-hypervisor), Windows 98 ran without the infamous “BSOD on startup” I recall from real hardware.
Perfect for legacy apps: I tested old games (Age of Empires, SimCity 2000), a Borland C++ 5.0 install, and a Visual Basic 6 project – all worked fine.

Cons:

No modern web browsing: IE5 is included, but HTTPS/TLS is ancient. You’ll need to transfer files via SMB, FTP, or a virtual shared folder.
Performance quirks: CPU emulation has to be slowed down (-cpu 486 or limiting speed) otherwise some games run too fast. Memory >512 MB can cause issues.
Not beginner-friendly: You still need to understand QEMU command line or virt-manager settings. The QCOW2 alone won’t “just work” on VirtualBox or VMware without conversion.
Potential malware risk: Since it’s a pre-made image from an unknown source, I scanned it offline first. Best to download from a trusted retro computing archive.

Verdict:
If you’re a retro enthusiast, developer testing legacy software, or just want to relive the ’98 experience without hunting for installation CDs and product keys – this QCOW2 image is a huge time-saver. Just be ready to tweak QEMU parameters and accept the limitations of a 20+ year old OS.

Tip: Use qemu-img to resize the disk if 2 GB isn’t enough, but keep FAT32 limits in mind. And always back up the original image before making changes.

Running Windows 98 within a qcow2 virtual disk image is a popular approach for retro-computing, as it allows for modern features like snapshots, thin provisioning, and compression that the original hardware never supported. 1. Core Configuration & Commands

To get started, you’ll need to create the virtual disk image and then launch the VM with specific hardware emulation that Windows 98 recognizes.

Create the Disk Image: Use qemu-img to create a 2GB to 4GB disk. While Windows 98 technically supports larger, staying under 2GB avoids potential setup prompts regarding "large file system support". qemu-img create -f qcow2 win98.qcow2 2G Use code with caution. Copied to clipboard Running Windows 98 in a modern virtual environment

Optimal Launch Command: The following configuration is widely cited for stability:

qemu-system-i386 -cpu pentium3 -m 256 \ -hda win98.qcow2 -cdrom win98se.iso -boot d \ -vga cirrus -net nic,model=pcnet -net user \ -soundhw sb16 Use code with caution. Copied to clipboard 2. Performance Optimizations

Because Windows 98 was not built for virtualization, specific "tweaks" are required to prevent the OS from feeling sluggish or crashing.

Enable DMA (Critical): By default, Windows 98 often has DMA (Direct Memory Access) disabled for the "QEMU Hard Disk," which causes extreme instability. Once installed, go to Control Panel > System > Device Manager > Disk Drives, double-click the QEMU Hard Disk, and check DMA in the Settings tab.

Role Change: Set the "Typical role of this machine" to Network Server under the Performance tab in File System settings. This speeds up disk access by increasing the size of the look-ahead buffer.

Cache Tuning: For the host side, you can improve qcow2 read/write speeds by increasing the L2 cache size in your QEMU command (e.g., -drive file=win98.qcow2,l2-cache-size=8M). 3. Known Workarounds & Troubleshooting

Modern CPU Crashes: Newer processors may cause Windows 98 to crash during setup. A common workaround involves switching the hard disk bus type to SATA in your VM manager to bypass standard IDE driver conflicts.

Graphics & Resolution: The default cirrus or std VGA drivers often limit you to 16 colors. It is recommended to use the SoftGPU or Scitec Nucleus drivers to unlock 32-bit color, higher resolutions (up to 1152x864), and basic 3D acceleration.

Network Drivers: The most compatible emulated network card is the pcnet model (-nic model=pcnet), as it has built-in drivers in Windows 98 SE. 4. Format Comparison: qcow2 vs. Raw Snapshots Native support; easy to revert Requires external tools or overlays Disk Space Uses only what is occupied (thin provisioning) Occupies full allocated size immediately Performance Slightly slower due to metadata overhead Maximum speed; no extra formatting layer

1. The RAM Limit Patch

Windows 98 crashes on startup if it sees more than ~1.5GB of RAM. Even with 512MB, you might get "Insufficient memory to initialize windows."

Fix: Edit system.ini in the [386Enh] section: MaxPhysPage=30000 (limits to 768MB).

Backup and migration

To export to a raw image:

qemu-img convert -O raw win98.qcow2 win98.raw

To compress:

qemu-img convert -c -O qcow2 win98.qcow2 win98_compressed.qcow2

To back up, copy the QCOW2 and any backing files, and export the VM launch command or libvirt XML.
