Well, unfortunately I don't know too much about kernels, but here is what I have gleaned at the moment: It seems to be possible to automatically disable APIC on certain motherboards. I found this out by checking the changelogs that the mandrake kernel developers wrote for the last two versions of the kernel: "- disable local apic in more boards." I've asked which files store the information on which board gets local apic disabled, but understandably I did not get a response. I've just checked with the latest kernel, and booting still does not work with acpi enabled, which means that the presario 7xx boards do not have local apic disabled. 2. For some uncomprehensible reason it is not possible to disable APIC by appending "noapic" at boot time. I've just checked with the latest kernel, and booting still does not So, unfortunately, you still have to recompile your kernel. But in all of this be aware that it is exclusively Compaq's fault, and Mandrake have got limited resources so they can't compensate for every hardware manufacturers faults. I've heard that some HP engineer is collecting information on which laptops need bios fixes for when they update the bios'es'. It might be a good idea to try and track him down, I think there was a message on cooker a while ago, maybe you can search the archives.
