Boot Block Recovery For Free
You don't need to pay a measly sum of dollars just to recover from a
boot block mode. Here it is folks:
AWARD Bootblock recovery:
That shorting trick should work if the boot block code is not
corrupted, and it should not be if /sb switch is used when flashing
the bios (instead of /wb switch).
The 2 pins to short to force a checksum error varies from chip to
chip. But these are usually the highest-numbered address pins (A10 and
These are the pins used by the system to read the System BIOS
(original.bin for award v6), calculate the ROM checksum and see if
it's valid before decompressing it into memory, and subsequently allow
Bootblock POST to pass control over to the System BIOS.
You just have to fool the system into believing that the System BIOS
is corrupt. This you do by giving your system a hard time reading the
System BIOS by shorting the 2 high address pins. And when it could not
read the System BIOS properly, ROM Checksum Error is detected "so to
speak" and Bootblock recovery is activated.
Sometimes, any combination of the high address pins won't work to
force a checksum error in some chips, like my Winbond W49F002U. But
shorting the #WE pin with the highest-numbered address pin (A17)
worked for this chip. You just have to be experimentative if you're
not comfortable with "hot flashing" or "replacement BIOS".
But to avoid further damage to your chip if you're not sure which are
the correct pins to short, measure the potential between the 2 pins by
a voltmeter while the system is on. If the voltage reading is zero (or
no potential at all), it is safe to short these pins.
But do not short the pins while the system is on. Instead, power down
then do the short, then power up while still shorting. And as soon as
you hear 3 beeps (1 long, 2 short), remove the short at once so that
automatic reflashing from Drive A can proceed without errors (assuming
you had autoexec.bat in it).
About how to do the shorting, the tip of a screwdriver would do. But
with such minute pins on the PLCC chip, I'm pretty comfortable doing
it with the tip of my multi-tester or voltmeter probe. Short the pins
at the point where they come out of the chip.
AMIBIOS Recovery bootblock:
1. Copy a known working BIOS image for your board to a floppy and
rename it to AMIBOOT.ROM.
2. Insert the floppy in your system's floppydrive.
3. Power on the system while holding CTRL+Home keys. Release the keys
when you hear a beep and/or see the floppy light coming on.
4 . Just wait until you hear 4 beeps. When 4 beeps are heard the
reprogramming of the System Block BIOS went succesfull, so then you
may restart your system.
Some alternative keys that can be used to force BIOS update (only the
System Block will be updated so it's quite safe):
CTRL+Home= restore missing code into system block and clear CMOS when
programming went ok.
CTRL+Page Up= restore missing code into system block and clear CMOS or
DMI when programming went ok.
CTRL+Page Down= restore missing code into system block and do not
clear CMOS and DMI area when programming went ok
Btw: the alternative keys work only with AMIBIOS 7 or higher (so for
example an AMI 6.26 BIOS can be only recovered by using CTRL+Home

Recovering a Corrupt AMI BIOS chip
With motherboards that use BOOT BLOCK BIOS it is possible to recover a
corrupted BIOS because the BOOT BLOCK section of the BIOS, which is
responsible for booting the computer remains unmodified. When an AMI
BIOS becomes corrupt the system will appear to start, but nothing will
appear on the screen, the floppy drive light will come on and the
system will access the floppy drive repeatedly. If your motherboard
has an ISA slot and you have an old ISA video card lying around, put
the ISA video card in your system and connect the monitor. The BOOT
BLOCK section of the BIOS only supports ISA video cards, so if you do
not have an ISA video card or your motherboard does not have ISA
slots, you will have to restore your BIOS blind, with no monitor to
show you what's going on.
AMI has integrated a recovery routine into the BOOT BLOCK of the BIOS,
which in the event the BIOS becomes corrupt can be used to restore the
BIOS to a working state. The routine is called when the SYSTEM BLOCK
of the BIOS is empty. The restore routine will access the floppy drive
looking for a BIOS file names AMIBOOT.ROM, this is why the floppy
drive light comes on and the drive spins. If the file is found it is
loaded into the SYSTEM BLOCK of the BIOS to replace the missing
information. To restore your BIOS simply copy a working BIOS file to a
floppy diskette and rename it AMIBOOT.ROM, then insert it into the
computer while the power is on. The diskette does not need to be
bootable or contain a flash utility. After about four minutes the
system will beep four times. Remove the floppy diskette from the drive
and reboot the computer. The BIOS should now be restored.
Recovering a Corrupt AWARD BIOS
With AWARD BIOS the process is similar but still a bit different. To
recover an AWARD BIOS you will need to create a floppy diskette with a
working BIOS file in .BIN format, an AWARD flash utility and an
AUTOEXEC.BAT file. AWARD BIOS will not automatically restore the BIOS
information to the SYSTEM BLOCK for this reason you will need to add
the commands necessary to flash the BIOS in the AUTOEXEC.BAT file. The
system will run the AUTOEXE.BAT file, which will in turn flash the
BIOS. This is fairly easy. Here are the steps you need to take.
· Create a bootable floppy diskette
· Copy the BIOS file and flash utility to the diskette

Talked to HP today (one hour!). Also talked to their support forum re: why they don't accept this as a problem with the Mobo on thier own support forum. They sent me back to the desktop support. $300 for a new Mobo. Don't think so. Ordered a new Intel board (mentioned above) for under $100. I won't recomend anyone to buy HP products, as I also had a laptop this week with the same problem, also not accepted as a problem. Big Company, little support, especially on these forums (don't you read them HP? We are just trying to fix YOUR products!)

Yep, HP couldn't care less once you buy their product. As I stated before, this computer was and will be the very last HP product I EVER buy. I am actually in the market right now for a new printer to replace my HP printer, and no way will I purchase anything HP. I honestly can not believe how little respect they have for their customers, when so many of us have had the exact same problem, yet they flat out refuse to admit their product has a problem. EPIC FAIL as far as customer support and satisfaction go.

Just checking in a year later to see if HP ever came clean on this one and I see that they have not. This remains very disappointing to me as I have bought and recommended many HP products over the years. I am a software architect that has been working in the computer field for 25 years and I am highly confident that this is a motherboard failure due to a defective part. I have never witnessed motherboards failing in these numbers after 1-2 years for a given product. The fact that HP will not acknowledge this mobo as a high failure rate part and support it under extended warranty is unjustifyable. They are clearly missing the boat on this one. I am a well-respected advisor on technology products to all of my friends and extended family and I am confident that HP has lost 5-6 sales over the last year alone based upon my guidance to others (and myself) related to this incident. I'm sure this will multiply into the dozens over the next twenty years. From the tone of others on this thread, I'm sure there are many additional lost sales there as well. Salvaging long term sales of tens of thousands of dollars by replacing a $100 motherboard under goodwill just makes good business sense (not to mention the ethical aspects of admitting your error and making good on your product). Oh well. Just thought I'd check back and hope things had changed, but I suppose I'm not really surprised. I suppose HP is more interested in making their quarterly numbers than preserving their reputation/brand for the long term. Too bad...

Just spoke on the phone to another rep and again they refused to acknowledge that there is a high failure rate with their product, again all the customer service agent could say was it is out of warranty period, and there is a fee to fix it. NO! This is at all acceptable! I will let everyone I know, know that HP will not admit they have a problem, nor will they do anything for a customer once the warranty has expired, even though a particular product has known issues. They refuse to accept and acknowledge this. Like I said before, I will NEVER spend another dime on any HP products, HP = FAIL! When I told the tech to do a search on their own forum and see what he finds, he told me there was no need to , my product is out of warranty,and I would have to pay a fee to get it fixed, that was basically all he said, no less than 8 times, he did not at all care about satisfying a customer, or keeping a customer, and flat out refused to read their own forum. I guess that repair fee was more important than losing all future sales from a customer. And I know I am NOT the only one, someone needs to read this forum and see what is going on, they ARE losing customers.

ALL HP PRODUCTS WILL ONLY WORK FOR FIRST TO SECOND YEAR AND THEN THEY DIE, I HAVE PURCHASED LAPTOPS, DESKTOPS,PRINTERS AND HP MAKES NOTHING BUT JUNK PRODUCTS. DO YOURSELVES A FAVOR AND BUY PRODUCTS FROM ANOTHER COMPANY.. HP SUCKS IN HONORING THERE WARRANTIES.. GOOD LUCK..

I am one of these HP suckers. Getting more and more distressed by the hour reading for three days all of these HP motherboard complaints. It makes me want to go postal!
Some where I read where someone was able to buy a mother board and put it in himself.
I'd like to try that as I can not afford the solution from HP buy another one of their pieces of JUNK!!!! Yet another slimline they can't get rid of for $469. Fool me once shame on you, fool me twice shame on me.
Can you help me find where online I can buy another compatible motherboard, since I can not find this mans post. It was not a "blue link" rather he wrote what he did and where he got it. Wish I could find that post been looking for 12 hrs. today, And I get seizures from being on the computer too long.
This is my computers specs:
HP Pavilion Slimline s3027c
Motherboard Specifications, M2NC51-AR (HematiteXL)
