Re: [ale] Gigabyte MoBo RAID and RH-7.2

[Michael Smith]

I have an Asus A7V233 which came with the Promise Raid stuff and I could 
never get it working with 7.2.  I now use the linux software RAID0 and I 
haven't had any problems(with the exception of the error correction on the 
Maxtor drive itself).
