The beep codes are not universal, but there are a few popular BIOS's and you can figure out what 2 beeps means if you can find your BIOS listed here:

The name of your BIOS should appear on the monitor as you're booting.

SOURCE: K8S-LA mobo heat sink fell off.

That is the 'Northbridge' chip that provides the I/O interfacing for the main chip. The heat sink is normally held on with glue as you surmised, and should be re-done with a thermal conductive glue. The glue (a silver filled epoxy) is available from MCM electronics or from Mouser. Be sure to thoroughly clean the chip and heat sink before re-gluing.

SOURCE: Bios ROM checksum error (Compaq SR5237CL with M2N68-LA MB)

A BIOS checksum error can be caused by a nearly flat BIOS battery.
I would replace the BIOS battery first before attempting to upgrading the BIOS.
Some motherboard BIOS firmware is upgraded by running a program that has been copy to a DOS boot disk or the upgrage maybe done from within the BIOS setup. These firmware upgrage and instructions are on the motherboard WEB site, in your case the Compaq/HP WEB site. Make sure you select the upgrade for your model motherboard.
NOTE it is possible that if you make a mistake you could ruin your motherboard, if you are not sure seek help from a computer savy friend.

Need to locate CMOS jumper on Toshiba satellite L505-13J for BIOS reset

There is no option to flash this motherboard's bios. PNY has not offered any BIOS updates and offers no way to alter the included BIOS. Sorry about that.

Sounds like your BIOS update did not complete successfully. Head to the board manufacturers website and check if there is some way you can reload the BIOS and recover from this. Most boards now have dual bios which means that if one bios chip fails or an update fails, you can reload the stored BIOS through the other chip. If you are unable to recover from a failed BIOS update, you may need to purchase a replacement BIOS chip from the board manufacturer. You may even be able to reload the original BIOS onto the chip through your local PC repair store so give them a call and enquire..

I was given an L500. It powers but fails to POST, this happened after a recommended BIOS update. Any kind of debug ports or something to sort this out?


After a BIOS update, if it fails to post, the BIOS update got corrupted. This happens (rarely) and when it does, the only thing that can be done is to remove the BIOS chip and have it burned at a local repair shop (or sent into Toshiba for a replacement). Without the BIOS functioning properly, the computer can do nothing at all. If your BIOS is not on a removable chip, then the computer will have to be sent to Toshiba to have the BIOS replaced.

Mobo Compatibility and tech/spec variations


All Asus P5GC-MX/1333 mobos are "X-series" boards.  

If you put higher speed ram on that mobo, it will just run the ram at lower speeds.

The board will not take 1333 speed DDR3, because it is only DDR2 compatible.

OVerclocking is complicated and risky, here is neither the place to teach or learn overclocking.

Some newer core 2 chips will automatically overclock, when all but 1 core is in hibernation (which will never happen if you are using vista). Other than that overclocking involves setting the bios to increase the memory buss speed, as well as slightly increasing the cpu and ram voltages as needed for stability. There is a great risk associated with manually overclocking and adjusting voltages, and should not be attempted by beginners on machines they value.

Serious issue with a proc upgrade for my Toshiba A65-S1062

BIOS UPLOAD


Ah, that is a nasty problem. Sounds like the BIOS got corrupted. You have several options:
1. Get another bios chip from the mobo manufacturer.
2. Get another motherboard and use it to program your bad chip. See here how
3. Dump the old mobo and buy a new one.

I would go with option 3. The other options are just a big headache.
