Re: ABIT BE6-II Posts, but can't enter BIOS

I got a replacement for this board, same model but v1.2 instead of v1.0. It has a newer Highpoint controller (HPT370 instead of HPT366). I think that's the only real difference.

I was able to get it cheap because only one memory slot is working. Could it be that replacing the caps will bring back the other 2 memory slots? The board is full of Jackcon capacitors. Jackcon appears on the bad cap manufacturer list

Re: ABIT BE6-II Posts, but can't enter BIOS

Already tried:
A different ram stick
Replaced ALL capacitors
USB Keyboard.

I didn't check the coils.

I think the issue is with the corrosion around the Winbond W83977EF-AW. I believe that it contains the keyboard controller. I desoldered the IC and there are corroded pads and and also corroded traces around and underneath it

I may attempt some micro surgery at some point and try to fix the traces/pads, but it'll be a miracle of if I can pull it off at...

Re: ABIT BE6-II Posts, but can't enter BIOS

Hmm, I can't see to be able to edit my post.

Anyway, I think it could also possibly be related to the W83977EF-AW I/O chip.

It looks like it will be fun replacing that

Hmmm, I actually noticed some corrosion or something on the pins of W83977EF-AW. I've tried cleaning it up with isopropyl. Maybe I need to reflow it

Re: ABIT BE6-II Posts, but can't enter BIOS

Ok, well that's disappointing.

I spent hours replacing all 27 capacitors and it didn't change a thing.

It posts, but I still can't get into the BIOS.

Should I look at trying to reflash the bios next?

Re: ABIT BE6-II Posts, but can't enter BIOS

Interesting. So replacing a cap near the battery fixed the issue? I've ordered replacement caps for the whole board, but I might try replacing the ones near the battery first. Thanks.

I also thought it might be something to do with the CMOS getting corrupt somehow. I'll try replacing caps first and take it from there ...

Mine POSTs, but I can't enter BIOS. Is that the same issue you had?...

Re: ABIT BE6-II Posts, but can't enter BIOS

Yeah, I also thought it might have been something like that. I'm going to recap anyway, but failing that I'd be interested in doing the BIOS reflash.

How would I go about doing it? Would something like this do the trick? [url]https://www.ebay.com.au/itm/CH341A-24-25-Series-EEPROM-Flash-BIOS-USB-Programmer/283083169035[/url]

I've also managed to score a cheap BE6-II v1.2 board as a backup. It was cheap because 2 of the memory slots don't work, so there might be another attempted repair job coming...

Re: ABIT BE6-II Posts, but can't enter BIOS

Thanks all. Yeah they are Tayeh. I'll do a full recap. I just wanted to see if it was worthwhile and was likely to fix this issue

Yes, I have. It was putting out 3v. I also bought a brand new battery to try....

Re: ABIT BE6-II Posts, but can't enter BIOS

Thanks for the reply. I could only see one cap bulging, which I replaced. I'm hoping it's another one that has gone bad, but isn't showing it

I was thinking of getting an ESR meter to test them without having to desolder the lot.

I'd be surprised if it's the PSU. It's a 750w Corsair HX that has been happily running a Ryzen 7 5700X and GTX 1080ti

Here's the pic:

Thanks!...

ABIT BE6-II Posts, but can't enter BIOS

Hi all.

A few years ago a built a kick-ass DOS/Windows 98 SE retro gaming PC with a an AGP Voodoo 3 3000 and ISA Soundblaster Vibra 16. It was working beautifully.

I pulled it out of the cupboard to play with it last year and it came up with a CMOS Checksum Error. I guess that was normal as it had been sitting dormant for a while.

The problem is, I can't get into the BIOS. When I power on it shows the VGA bios screen, then it shows the CPU type, does a quick memory test, looks for a Primary Master HDD. Then it says "CMOS Checksum Error - Defaults...
