Hello, I tried to compile ataraid under RH7 and kernel 2.4.6, but in this kernel, the GFP_BUFFER def has disappeared... I would like to try with the recommended 2.4.6-ac kernel and would like to know what mean 'ac' ? What i have understood is that booting on a raid array is not proved to work ... that means there is a chance it does ;-) >From http://www.thedukeofurl.org/reviews/misc/promisehowto71/, i read "I disagree with how these are put together (they just treat the FastTrak card as an IDE device, not a SCSI device), but they will do the trick for users who need open source drivers. " What does it mean ? Is it a bad thing that the card is being seen as an IDE device ? For information, i have a 694D Pro AIR mb, with a built in PDC20265 Promise FastTrack-Lite 100 raid controller. Thank you for any help ! Greg
