recently I toyed around with an ASUS P3B-F, and obviously I came across the modified "Noa" BIOS for this board. While effective, I disliked the way some of the changes were done, so I decided to re-do everything (and add a little bit more). Maybe somebody else can make use of it. The mod is based on the last official beta BIOS 1008.004 and includes the following changes:
- support of multipliers 12.5x through 16.0x on the "Advanced" tab of the BIOS Setup Utility, including display of suggested CPU speeds for standard FSB speeds
- support of displaying normalized frequencies at bootup for multipliers 12.5x through 16.0x at standard FSB speeds
- fix for the display of processor brand names at bootup, including support for Pentium III-S processors
- fix for the display of frequency suffixes (A, E, B, EB) at bootup according to Intel datasheets
- support of additional voltage ranges to suppress Hardware Monitor errors at bootup
- updated processor microcodes
- fixed display of multiplier 2.0x for processors with Klamath core (P3B-F and P3V4X)
- unlocked core voltages for undervolting
- added Setup Utility "Enable" option for Symbios SCSI BIOS to force loading the ROM module even if no matching adapter is present
- CUBX: updated CMD Ultra66 ROM to version 1.9.16
- CUBX-E/L: updated Promise Ultra100 ROM to version 184.108.40.206
- POST fixes for Pentium Pro processors (P3B-F and P3V4X (latter untested))
- fix for the "Processor Version" and "Processor Family" fields in SMBIOS
All BIOSes seem to work fine here. Still, make sure you have a working crisis recovery procedure before attempting to use them.
