WhizPro BIOS password

[pentium]

I have an OEM board here with the model SL-810 from BCM which again is some weird OEM company who barely supports this.
I say barely because while a page for the motherboard exists all the links both now and according to the wayback machine which would remotely help me are all broken. Furthermore my board has a password set on the BIOS and it isn't clearing with the CMOS battery removed. It isn't totally locking the machine down however as I can still boot from an optical drive (but not the floppy ) but I've already gone through it with the BIOS tools on the Hirens Boot CD and nothing seemed to work. The weird "WhizPro" BIOS isn't something any of the tools expect. I need something a little bit more powerful but I do not know what else to try. Any suggestions?

Re: WhizPro BIOS password

Maybe same layout as their SL620, which is only S370/LPX board listed on BCM support page

Does your SL810 have a JP2/Clear CMOS jumper in the same place as SL620 ?

Re: WhizPro BIOS password

The layout appears to be wildly different unfortunately.

What about compared to FX815ELT ? - only other Wizpro BIOSed board from their Socket 370 range

Or SL5598 ? - only LPX board from their Socket 7 range

Otherwise, sorry - hope for response from your post on Vogons

Re: WhizPro BIOS password

Nope. None of those match up. :/

if the cmos jumper suggested from boardl cannot work,
you can try pull the winbond chip bios, and read using bios programmer like : cheap nanobios programmer..

post here your backup file, i'll try to clean your bios..

Re: WhizPro BIOS password

I have a Willem Ver 5.0 unit that can dump the chip but it is being very inconsistent with this chip so far unless my settings are wrong.
I can however dump the chip while it is in the machine. I got more than enough tools for that.

Re: WhizPro BIOS password

How long did you leave the CMOS battery removed ?

I'd try leaving it out overnight, the Irish technique (to be sure, to be sure)

Re: WhizPro BIOS password

It was out for two weeks minimum.
Where the board came from initially I regularly see them come with flat CMOS batteries anyways. This could of been missing a backup battery for years.

that has worked for me more than once in the past!!!

Re: WhizPro BIOS password

I'd focus on getting a reliable read of the BIOS EEPROM. Given the age of that thing and since it's not in CMOS, the password is likely to be stored as plain text in EEPROM.

Re: WhizPro BIOS password

It's a 49LF004A. It's still quite new.
Also, I already dumped it. Poling through a hex editor however has not yet found anything.

Re: WhizPro BIOS password

If you got a good image check if you can disassemble it using tools leaked on the internet. Unless it's a Compaq BIOS it's likely to be some variant of AMI, Award or Phoenix which can be taken to bits.

Re: WhizPro BIOS password

hey Pentium.. do you recall ever getting into this board? I have one with a BIOS PW as well and swapping almost all of the jumpers around hasn't cleared the CMOS PW

[pentium]

Re: WhizPro BIOS password

Nope.
The dumps I did get were inconsistent so I don't trust my Willem with reading the FWH chip correctly. I was able to locate the CMOS clear jumper and while that did indeed clear the CMOS it immediately sets the password again, so that's a BIOS default parameter. I don't think I have ever seen something do that.

Because I couldn't crack the password I moved on from this board.
