I have windows 98 and 2000 on 2 psysically different hard drives. It doesn't give me an option to select the OS during boot up. Only way now i can boot up with different OS to change the booting sequence for HD in the BIOS settings. can anyone tell me how to set it up to get the choice during boot up.. not changeing the bios setting all the time? the motherboard i have is Impression 771 AS (for slot A Athlons)
