Default Re: IPIBL-LB loses BIOS settings after power off

Do you use the same HDD for Windows 7 and XP?
When you install the OS are you connected to the internet via a firewall?
Have you zero filled (wiped clean) the HDD before installing OS?
Have you scanned your installation and update media for rootkits?
Trying to narrow down if hardware or software problem
Your PSU has not been ruled out nor has the CPU as yet.

No switches connected - just motherboard on a wooden surface, touching jumper momentarily to necessary places

Yes, using manufacturers' diagnostics

No, but I am using Win7 SP1 with update, downloaded from Digital River when it was available, and SHA1 checked before burning to DVD

And same DVD has been used many times, without issue

Have tried multiple PSUs and CPUs

So I need to remember to use Ctrl-Alt-Del for reset

Something fundamental seems to have gone wrong with its electronics - reckon I'm
That is quite strange, indeed.
My IPIBL-LB is in a HP PC, so it doesn't have a reset switch. But wonder if will do the same thing. If not, then for sure something may not be quite right with yours.

With that said, perhaps consider giving the motherboard a wash with detergent and warm water, then dry for a few days. Maybe something conductive has gotten under one of the chipsets and is shorting something? I know that using case screws with non-smooth heads will sometimes produce solder and/or metal shavings where the screw head grinds against the motherboard or case. If these shavings got underneath a BGA chip, I think that could cause intermittent trouble. So when in doubt, I wash things and make sure to force plenty of water under whatever BGA chip I think may have gotten affected. Never really had a case where resolved anything, but for the tiny off-chance that it might be possible, I still do it.

Another thing to try if you have a seperate chip programmer, reflash the bios chip, that will clear it out for sure. Or buy another chip with the bios preprogramed.
I had a Epox motherboard that would stop posting with a C1 error and could not flash on board so took it out and reflashed in programmer now works fine.

KUDOS to Sparkey55

I desoldered its MX25L8005 BIOS chip and reflashed it with my Rube Goldberg setup - https://www.badcaps.net/forum/showpo...55&postcount=9

Involving:
1. Erase
2. Blank check
3. Program
4. Verify
5. Dump
6. Compare dump to original

So it should have been well & truly cleared out

Didn't feel that confident after all the setbacks along the way, but after the acid test of booting an existing Win7, then shutting it down and turning the power off, it didn't produce the dreaded message after starting again

Even left it powered off overnight to confirm no message in the morning, before posting this

Has certainly reinforced my opinion about Macronix chips being cheap & nasty, compared to Winbond or SST

Thanks to everyone who contributed

Yay! Good to hear a success story here!

I wonder if that got rid of the random BSODs you experienced too.
I raise this question, particularly because I pulled my HP PC with the same motherboard, and first several boots, it was doing some weird things, including throwing a BSOD once or twice. But after a day of use, all trouble went away. I then turned off and disconnected the PC for a few days to see if the issue is perhaps cap related (it does have a Bestec 250-12Z PSU that hasn't been recapped... though all caps appear OK visually... which we know doesn't mean much, but still.) So far, though... it's been OK.

Anyways, I'll keep this thread in mind if I see any more odd behavior with my board. In any case, really glad that you were able to fix your and that you updated the thread.
