eprom programmer

[Christopher Howe (deadman83)]

eprom programmer does any one have one as i have a computer that has a bad bios and want to try and reprogram it to see if i can get it working

[Alistair MacDonald]

I think I have seen a couple knocking around. What type of EPROM are you needing to flash? I will check if it is compatible.

All the best,

A serial usb programmer is in the space I donated years back.

Works fine for most.

Worth noting - is it a socketed EPROM/EEPROM, or mounted to the motherboard?

You'll need to know the IC type number for certain before we can tell for certain if we can help program it.

That is a little more modern than I was thinking. This is likely not in fact an EPROM or an EEPROM, but simply flash storage. Depending on the type you may be able to use a simple Arduino to reprogram it. It all depends on what it is, and if you can’t read the chip we just don’t know.

There is one obvious question though. What makes you think it was the BIOS at fault? Did it fail in an update or something like that?

All the best,

FWIW, from the Lenovo manual:

Recovering from a POST/BIOS update failure

If the power to your computer is interrupted while the POST and BIOS is being updated, your computer

might not restart correctly. If this happens, perform the following procedure to recover from the POST and

BIOS update failure. This procedure is commonly called Boot-block Recovery.

1. Remove all media from the drives and turn off all attached devices and the computer. Then, disconnect

all power cords from electrical outlets and disconnect all cables that are connected to the computer.

2. Remove the computer cover. See "Removing the computer cover" on page 77.

3. Locate the Clear CMOS /Recovery jumper on the system board. See "Locating parts on the system

board" on page 72

4. Remove any cables that impede access to the Clear CMOS /Recovery jumper.

5. Move the jumper from the standard position (pin 1 and pin 2) to the maintenance position (pin 2 and

pin 3).

6. Reconnect any cables that were disconnected and reinstall the PCI card if removed.

7

. Reinstall the computer cover and reconnect the power cords for the computer and monitor to electrical

outlets. See "Completing the parts replacement" on page 123.

8. Turn on the computer and then insert the POST and BIOS update (flash update) disc into the optical

drive. Wait a few minutes. Then, the recovery session begins. The recovery session will take two to

three minutes. During this time, a warning message will be displayed and no action is needed from you.

9. After the recovery session is completed, there will be no video, and your computer will automatically

turn off.

10. Repeat step 1 through step 4.

11. Move the Clear CMOS /Recovery jumper back to the standard position (pin 1 and pin 2).

12. Reconnect any cables that were disconnected.

13. Reinstall the computer cover and reconnect any cables that were disconnected.

14. Turn on the computer to restart the operating system

Would be a nice fix if that works - apologies if you've already tried...
