I'm in a similar situation: 2 big HDDs (40, 60 GB). Have Promise HDD controller.
However, I want to also install WinNT 4, SP6. How do I go about this?
Can I just install W98SE, then NT, then Win2k? Do it all on one of the HDDs? Does the C: partition need to be FAT or can it be FAT32?
As I understand it, the 3rd boot OS should start before 2 GB limit has been reached, so I plan to make Win98 around 800 MB, WinNT maybe 1 GB, and give Win2k 4 or 5 GB. I will use Win2k 99+% of the time, and am installing the others just for testing problems I may have in Win2k for one reason or the other. I may even have apps and data for NT and W98 in their own OS partitions, since they will be lightly used.
