if it aint broken then dont fix it unless your willing to go all the way . win 98 is still the better gaming platform . in my opinion.
But XP pro seams to be working pretty good, except for the fact that everything isnt updated to work on it yet , and its a ram hog it uses 128mb vs 32 mb .
also if your going to XP you have to compleatly scrub your old OS off your Hard drive (I mean Fdisk and reformat ) DO NOT INSTALL ON TOP OF AN OLD OS !!!
As for the duel boot set up it works fine for me on a dual hard drive system and you have to enable the OS that you want to run in the bios/dos setup screen as you turn on the pc for it to work trouble free. (But note here two hard drives each one with 1 OS and correct drivers installed ) Some people say a partitioned single hd will work, but i havent tried it with 98 and xp yet .
now My inlaw and I tried a duel boot on a Raid system (Iwill 333 mb, 2.0 AMD xp cpu, 1.5 gig ddr) 2 matched hard drives running the raid w/ win xp on them and then a 3rd drive with win 98se on it .and the results are as such.. the first 3 times we switched it back and forth between the systems it worked fine ...
the 4th time we switched down to 98se then back up to xp .. the whole mess crashed (and I mean crashed badly) had to fdisk the whole mess and start over .it would not even repair itself with the system disc. and or reload either OS (we havent tried the dual boot system again yet because it just wont work on this combo )
A note on the Raid systems (dual hard drive striping simutanalisly)
They just SCREAM !! it loads 2+x's faster then a single hd system.
well thats all i know ...and current results from the "Roo" PC labratory ...
