[dba-Tech] Re: RAID definitions etc

...if both of the motherboards are WinXP certified by MS and you have the
new mb drivers, then the OS should be repairable from the CDs ...if not
you're working in lala land ...the reason I buy/recommend nothing that isn't
on the MS list ...I don't care what the salesman or the manufacturer says,
if its not on the MS list, its not purchased.
