Well, I found a workaround for Win98/DOS diskettes not booting. The Windows 2000 CD would boot, so I've installed it. I've done the SP2 so that I can put back bootmanager(2000 corrupts it), and have downloaded all the drivers off IBMs site for the T22.
Ran into a problem with DVDexpress though. The driver is an UPGRADE only driver. I chose to format the drive when installing 2000 because I've seen enough "upgrade" problems to not want to do that. I checked out the contents of the recover partition, but it looks like it's a "drive dump" as I cannot find individual items to install out of it.
The other "problem" I have is that Win2000 shows drive letters for my OS/2 partitions. Is there a way to hide them from Win2000?
