Thanks for the warnings.
If Abit didn't like the performance of the HPT370 chip, then why bother
putting it in my KT7-RAID mainboard? Is it because of the term RAID sounding
It looks from the change logs that i will have to go beyond kernel 2.4.18
because of a lot of USB changes. So i will try to upgrade the latest kernel
and load the HPT370 driver module. If that doesn't work, i'm going to say
farewell to my semi-RAID.
I still consider myself a newbie and don't know anything about software
