Sadly, booting linux seems to be next to impossible - bootup works on debian boot-floppies kernels (2.4 and 2.2-based) but spews out the following error, in great volume, on all my kernel compiles: APIC error on CPU0: 04(04) The occurs immediately after boot, at which point this message floods the screen until I hard-reset the machine. A couple of google searches yielded nothing too informative- I've found some references to the Abit BP6 board having similar problems, this being due to a faulty APIC implementation by the mobo manufacturer. I also found one other person with the same problem- he finally managed to boot by disabling APIC in the kernel config as below. I've tried 2.4.19, 2.4.20 and 2.5.62 kernels, smp enabled or not. I've tried passing noapic or disableapic to lilo at boottime/append. I've tried going into .config (I usually do this through menuconfig) and undefining or setting =n to all references to APIC (ie. CONFIG_APIC_GOOD=n, CONFIG_IO_APIC=n, CONFIG_APIC_LOCAL=n). All to no avail. I have yet to try 2.0 and 2.2 kernels, but I would rather not, as I really need the features in 2.4 I'm very much in hope that someone here can help me... I'm an experienced linux user, but this is my first try at smp and I don't know what an apic is. -kacper
