To install Win98 on the second drive, do this:
1. Disconnect your first drive.
2. Connect the second drive as the primary master.
3. Install Windows 98.
4. Test it.
5. Connect your Win2000 disk as the primary master.
6. Connect your Win98 disk as something other than
the primary master.
7. Boot the machine with a Win98 boot disk from
www.bootdisk.com.
8. Install the free boot manager XOSL in the existing
Win98 partition. Do NOT select "dedicated partition" -
this would erase your Win98 installation.
9. Add Windows 2000 and Windows 98 to the XOSL
menu.
10. Instruct XOS to switch disks when booting into Win98.
