Windows 98 Qcow2 2021 Full
If you create an image larger than 2GB, the Windows 98 setup will prompt you for "large disk support" (FAT32); you should select 2. Recommended QEMU Launch Command
qemu-system-i386 -m 512 -cpu pentium3 -vga cirrus \ -drive file=windows98.qcow2,format=qcow2 -net nic,model=pcnet \ -soundhw sb16 -device usb-mouse Use code with caution.
The -net nic,model=pcnet flag emulates an AMD PCnet PCI Ethernet card. Windows 98 SE contains native drivers for this card. Go to Network Properties in the Control Panel. Ensure that is bound to the AMD PCnet adapter.

If you’re a retro-computing enthusiast, Windows 98 represents a high-water mark of the DOS-based era—a time of pixelated icons, the birth of USB, and the legendary startup sound that defined a generation. But running it on modern hardware is a nightmare of incompatible drivers and hardware that’s simply "too fast" for 90s-era kernels.
-m 512 : Allocates 512MB of RAM. Do not allocate more than 512MB initially; Windows 98 will crash with "Out of Memory" errors if it detects more than 1GB of RAM without manual system configurations.
Provides essential USB storage drivers for Windows 98 SE. If you create an image larger than 2GB,
qm importdisk 100 windows98_full.qcow2 local-lvm --format qcow2 Use code with caution.
Windows 98 lacks native support for large hard drives. Without patches, enabling a virtual drive larger than 32 GB can cause data corruption. Updated IDE/ATA drivers allow the QCOW2 image to scale up safely. Graphics and Audio Configuration
-cpu pentium3 : Emulates a single-core legacy x86 processor to avoid timing bugs. Windows 98 SE contains native drivers for this card
You can run Windows 98 in VirtualBox or VMware, but you will hit a wall. VirtualBox dropped support for Windows 98 Guest Additions years ago; 3D acceleration is broken, and audio stutters. VMware works better, but the free tier is limited, and snapshots are clunky.
If you don't trust pre-built images, build one in 15 minutes:
qemu-system-i386 -m 128 -M pc -vga cirrus -net nic,model=pcnet -net user -fda bootdisk.img -cdrom win98se.iso -hda windows98.qcow2 -boot a Use code with caution.
Running Windows 98 today often requires using a virtual machine, and for QEMU or KVM users, the (QEMU Copy-On-Write) format is the standard for virtual disk images. This format is efficient because it only takes up space on your host machine as data is added to the virtual environment.
Most users resort to VirtualBox or VMware for retro virtualization, but both platforms have dropped or severely degraded support for 16-bit/32-bit legacy operating systems like Windows 98. QEMU, combined with the QCOW2 format, stands out for several reasons:
