Hi,



   After playing with it for a while, I decided to turn to the list for
some clues.

   I have on my hands a workstation, based on a Intel Desktop board
D875PBZ (875P chipset), with a Pentium4 2.4C processor. This workstation
has 3 disks, one being a ATA100 drive (system disk), and two SATA drives
(data).

   I installed RedHat 9 on it, knowing that the default RH9 kernel
(2.4.20-8) wont work well with HT, nor will it recognize SATA. But that is
why I bought it with an ATA drive for system.

   Anyway, after that, I went to upgrade the kernel to 2.4.20-20.9 (latest
RH kernel). I know that the HT support is suckie for now, so I disabled HT
in the BIOS (although all you'll see below was also tried with HT enabled,
and with both SMP/non-SMP enabled kernels).

   Now, I have the following options installed:

2.4.22-ac3 / 2.4.22-ac3-smp (self compiled)
2.4.20-20.9 / 2.4.20-20.9smp (RedHat kernel)
2.4.20-20.9custom / 2.4.20-20.9custom-smp (RedHat kernel self compiled)

   With 2.4.22-ac3, without (or with) HT, the system just reboots
immediately after "booting kernel blah", and the interrupt mapping stage
(forgot the name, it has a specific name, that stage).

   With 2.4.20-20.9, when HT is disabled, the system boots up until it
tries attaching ide-driver to the hde device (the first out of two SATA
disks), at which time it freezes. When HT enabled, it just reboots, same
as 2.4.22-ac3.

   With 2.4.20-20.9custom is more or less the same as the RedHat released
kernel.


   In any case, I can do without HT for now. However, I cannot do without
the SATA disks. I did manage to make this work on a 865PERL based
motherboard 1.5 months ago, with 2.4.21-ac1 or something. I assume no one
broke the IDE kernel driver since, but I am not sure.

   Does any of you have experience with this motherboard, and made it work
properly with/without HT but WITH SATA working ?
