Bios Mods -The Best BIOS Update and Modification Source

Hoping that somebody can help me.

I was goofing around with the SLIC table in my BIOS and may have fudged something.

My M/B still POSTs + boots fine and almost everything works but I believe that I may have messed up my onboard LAN in the process.

My motherboard is an OEM Asus made for HP -> P5BW-LA (Basswood3G-UL8E version) HP part# 5188-7408

There is no softpaq available from HP that I could find for this M/B, even though there are for the Buckeye, Basswood and Basswood2 variants.

Initially, my onboard Intel 82566DC was working fine under Windows 7. Then I extracted my BIOS with awd865.exe, ISA modified the SLIC table and reflashed it with awdflash.exe v1.34.

What makes me believe that I messed up my onboard LAN is that after flashing and upon rebooting, Win 7 recognized and installed drivers for LAN Connection #2 for "another" Intel 82566DC LAN device, abandoning the original LAN Connection as though it was uninstalled. Result, onboard LAN is still recognized but no longer works.

I reinstalled Windows 7 which put me back to one LAN Connection but still no worky.

Also, if I enable the LAN Boot ROM, I get a corrupted LAN EEPROM error during POST. I don't know whether that would have happened anyway pre-flash as I never tested that pre-flash.

I flashed back my unmodified BIOS but still have the same problem.

Anyway, I guess that I can't be 100% sure whether I actually corrupted something in the ROM chip or if my onboard LAN just decided to get funky on it's own. But I'd bet that it had to be what I did

I suppose other possibilities are that my original extraction was faulty or that my method of flashing is flawed.

BTW, I flashed with award flash v 1.34 (no SLIC checks) via ...

awdflash BIOS /py/cc/cp/cd/r

So I wonder ...

Is the onboard LAN BIOS contained in that same 1MB M/B BIOS chip with everything else ? So could I have even of whacked it ?

I would appreciate if anyone has a copy of the ...

Award Broadwater P5BW-LA3-00 v5.09 6/08/2007 BIOS ?

and could post either the BIOS itself or even a checksum that I can compare against the pre-mod version that I had extracted ?

I did happen upon a 5.07 version for the same M/B out there but I'm a bit gun shy to try that.

Anyway, happy Sunday

Here ya go! two to choose from
remember to always make a backup! lol

Thank you so much for taking the time to reply. I really appreciate it

I did do an initial backup of my BIOS but I think that I may have used the wrong tool (awd865.exe) such that the LAN EEPROM info was not properly extracted with the rest of the BIOS, if that's possible.

I don't seem to be having much luck in finding an expert with such knowledge so far

Unfortunately, the 2 BIOSes contained within this download are NOT for the Basswood3G.

The 317.rom is for the Buckeye and available from HP as sp35153.exe and the 508.rom is for the Basswood2 and available as sp26920.exe. The other one out there is for the Basswood and it's HP sp24029.exe.

This P5BW-LA is a tricky beast and as it comes in 4 distinct flavors ...

Buckeye
Basswood
Basswood2
Basswood3G

and all of the BIOSes are different and I'd assume that flashing any with a version from one of the others would produce an instant brick

In doing some additional research, I now have conflicting info on the 508.rom(sp26920.exe) but HP's site seems to indicate NO as there is no link to it from any of the systems with the Basswood3G M/B. Yet there are links to it from systems with the Basswood2 M/B. So I'm not chancing that puppy.

Therefore, if anybody has a BIOS, preferably v5.09 that they KNOW came from a P5BW-LA Basswood3G, I'm still searching.

This M/B resides in any of these HP systems ...

Thanks again !
