Description Need Real Name 2000-08-14 17:59:02 UTC
When booting Redhat 6.2, I get an error message and the system locks up. At
this point, it is not possible to page up to view the text that is not 
visible on the screen. This does not occur when booting from a boot 
diskette. I booted up from a diskette and recompiled the kernel according 
to the SMP How To. It says that you must 1. Enable SMP support, 2. Enable 
Real Time Clock support, 3. Disable Advanced Power Managment  4. Enable 
Memory Type Range Register. The MP table in the bios is set to version 1.1.
I tried MP table 1.4 but it also crashes.

The board that I am using is a dual 700Mhz pentium III slot 1 processors 
w/256K on board Die cache w/128 MB dimm mem module w/ ecc 100mhz FSB

2 - enet
1 - scsi
1 - parallel
1 - serial

When I boot up linux and type: linux noapic, the computer boots fine but in
Single processer mode.

Please advise me what to do to fix this so I can run in SMP mode.

This is the error message that I am getting:

 ..... system bus clock speed is 0.000 Mhz Error: only one processer
found. ENABLING IO-APIC IRQs no explicit IRQ entries,using default mptable

This does not look like a happy machine. The fact booting noapic comes up single
CPU strongly suggests that. 

Comment 2 Perry Harrington 2000-12-10 06:44:42 UTC
I would suspect that the BIOS is horribly in need of an update.  The data being
fed to the kernel by the BIOS at boot is probably messed up.  Try a later BIOS
