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 itLast edited by chromium; 01-23-2021, 02:25 AM.

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...Last edited by chromium; 01-11-2021, 01:45 AM.

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

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