PCServer704/Netfinity7000 - Clear CMOS procedure change
Applicable to: World-Wide
If the "switch" procedure (clear CMOS with J6A1-1 after BIOS update) is done on a Netfinity 7000, there is the possibility that the PCI cards will get assigned the same IRQ as Advanced System Management Adapter (ASMA). If this happens the system will hang during boot. The only workaround at this point is to remove all ISA adapters, and then boot into the SCU and redefine ISA adapters (ASMA specifically).
Therefore the whole clear CMOS procedure has been changed. By doing the "f1,f5,f10" method, the ASMA configuration remains in NVRAM and the PCI cards can never take that IRQ. The "switch" method will clear NVRAM as well as CMOS causing the hang problem. This is important since every Netfinity 7000 will ship with ASMA. The same procedure applies to the PC Server 704 systems.
The f1, f5, f10 is now considered the best way to clear CMOS after doing a flash update of BIOS because of the fact that you will not have to redefine ISA adapters. However, the "switch" method is still a valid method to clear CMOS. The BIOS 10 readme.txt does not reflect this because BIOS 14 will be released shortly.
The next release of BIOS for Netfinity 7000 and PC Server 704 (BIOS 14) will not require that the CMOS be cleared in any form, and the readme files will reflect such.
