That was the approach I wanted to use in the first place to deal with the broken local apic in vmware 2.0.4. See the thread (which is unfortunately broken -- the followup must not have included a References: header back to the my original message): http://www.ussg.iu.edu/hypermail/linux/kernel/0305.3/0907.html The thread can be picked up again in this message: http://www.ussg.iu.edu/hypermail/linux/kernel/0305.3/0995.html > "nolapic" is > simply a workaround for the absence of this DMI data. Unfortunately, VMware 2.0.4 does not have any DMI data to identify it by. the search for _DMI_ between 0xF0000 and 0xFFFFF finds nothing. I dunno if this is valid for proving or disproving the presence of DMI data, but: # dmidecode # dmidecode 1.8 BIOS32 Service Directory present. Calling Interface Address: 0x000FD8C0 PNP 1.0 present.
