Re: Pata support on Promise controller under Fedora Core 3

["James C. Bevier" <jbev@jbsys.com>]

Ericisko,

The disks are two identical Western Digital 160 GB drives.  They are
seen by Windows XP and were seen by the Promise driver under
Linux 2.4.  I have the BIOS set on the K8V SE Deluxe motherboard
to be non-raid disks on the Promise controller.  The first drive has
two NTFS partitions and the second has three Linux partitions.  Hda
& hdb are 80 GB drives and hdc & hdd are DVDROM & DVD Writer.
I was able to read the NTFS files and did not experience any lock-ups.
I have an Athlon64  3200+ and am only running the 64 bit version of
Fedora Core 3 RC1.

I will do some more testing to see if I can see the second drive.
Thanks for the information.

Jim
