Does anyone know which desktop versions of SuSE, if any, support or will work on P4 machines with Hyperthreading enabled?

Was trying to install 8.1 Pro on an IntelD865GBFL w/HT enabled and though it would boot from the CD, it could not mount the CD for install, nor could it identify any IDE devices at all.

Suspecting it is the HT, can anyone confirm/deny or shed light on it? The hardware DB states nothing remarkable either way about the Intel D865G board/chip.

Which kernel (2.4.?) supports P4 Hyperthreading?

The 8.1 default kernel (2.4.18, wasn't it?) supports hyperthreading, though I've only tried that with Xeons. I've used and am using 8.2 with Dell GX270 (865G chipset, P4), and hyperthreading switched on - no problem. Comes up as a dual CPU system with an SMP-enabled kernel.

Any error messages, any more data on hardware?

I have only done HT on Xenons as well but some boxes require the acpi=oldboot or even acpi=off flag on the boot prompt Regards Hubba

Thanks for the replies. Have tried IDE=NODMA, ACPI=OFF and APM=OFF. Only thing of note is a message about an unknown IDE controller at PCI BUS 00 Device fa VID=8086 DID=24d1 as well as IDE not being in 100% native mode. I also tried turning Hyperthreading off in the BIOS as well as the Intel Quick BIOS boot option. All to no avail so far! More suggestions welcome! At 01:49 PM 11/14/2003, you wrote:
