the CPUs are active in the BIOS. The BIOS is v 1.05. with 1.06 being
the very latest.
According to IBM the changes from 1.0.5 to 1.0.6 are
* Added in serial remote console redirection
* Fixed PXE ROM execution failure when using PXE on planar Ethernet #2
* Removed the "Auto Configure" IRQ option for the System Service
Processor IRQ setting in POST/BIOS setup to prevent erroneous
configuration change and diskette drive failure messages
I have a number of these machines running linux with no problems.
