Windows 98 Qcow2 Full May 2026

qemu-img create -f qcow2 -o preallocation=metadata win98.qcow2 2G

| Problem | Likely Fix | |---------|-------------| | Black screen on boot | Set -machine pc,accel=tcg if KVM fails. | | No mouse in window | Add -usb -device usb-tablet. | | “Windows Protection Error” | Add MaxPhysPage=30000 in system.ini (for RAM >512 MB). | | No network | Use ne2k_pci or rtl8139; enable DHCP in 98. | | High CPU idle | Install RAIN20.EXE in startup. |

Summary

CD-ROM: attach installation ISO with -cdrom win98.iso -boot d.

Network: use e1000 or rtl8139 (rtl8139 is commonly supported by Win98 with drivers).

Video: cirrus-vga is compatible; VNC/SPICE for display.

Example qemu-system-i386 command (concise): qemu-system-i386 -m 256 -machine pc -cpu pentium2 -drive file=win98.qcow2,if=ide,format=qcow2 -cdrom Win98SE.iso -boot d -net nic,model=rtl8139 -net user -vga cirrus

Install VirtualBox/VMWare tools are not applicable; instead install QEMU guest agent is not available for Win98—use generic drivers and manual configuration.

QCOW2 features: enable compression during image creation if disk space matters (qemu-img convert -c).

Memory: set to 256–384 MB for snappy behavior.

CPU: select an appropriate CPU model to avoid unstable behavior from too-modern features; avoid enabling too many virtualization extensions exposed to the guest.

Explanation:

Windows 98 lacks drivers for QEMU’s default hardware. Use QEMU Guest Tools for Win9x (unofficial). | Problem | Likely Fix | |---------|-------------| |
