QEMU/KVM Notes

Pre-Installation Notes

The CD-ROM drive sometimes doesn't show up after first reboot. In order to continue installation, be sure to copy the install files to the hard drive first. Somewhere like C:\Win98.

Be sure to patch the installation files too with Patcher9x before installation.

To enable PCI hardware detection in QEMU/KVM:

  1. Open Device Manager
  2. Right click Plug & Play BIOS and click Properties
  3. Select Update Driver, then Display All Drivers, then select PCI Bus.
  4. Reboot
