Is your post time slow? Thats my main issue, I'm using a solid state drive windows boots lighting fast ( 2-3 seconds I'd say) but the post time really slows me down . Note I'm using full version of XP with minlogon and EWF (no HORM).
Finding motherboards with really fast post times would probably be the biggest decrease in boot times for most of us.
Which Mtron drive are you using if you don't mind me asking?
