Still struggling with this thing. I put a diagnostic card but (4 digit display), but I see no numbers whether I put it in a ISA or PCI slot. Only - - - - So it should be powered up but no other signals I guess. Strange.

Thank you for this! It is a start, but it lacks all the other general settings on voltage low to 2.0 and multi up to 5x (assuming 6x is equal to 2). Looking for someone willing to mod the bios.

Hello, I found this motherboard, never knew Daewoo produced motherboards… It seems a solid motherboard, but it does not boot (on/off button works though). there is no info on it apart a retroweb page and this page with a lot of details. http://musaran.free.fr/CB581X-VI/CB581X-VI_E.html Problem is, …

The original chip was bricked. I flashed the new one with the programmer and the board booted without issues. Thank you for forcing me to buy the T48! Aaaand…. Success!!! Yay, good job! :) So, what did you have to do to get it working? New chip? Used the 27 series one? Got the original chip back to …

Ah, sorry, was under the impression you got the device ID (1FD5) by reading it from the actual chip with Uniflash. If you can't read it correctly in any way, then yes, your chip (or something else in the HW chain) might be busted. That's a 27 series chip that needs 12V programming voltage, …

The only way the software could identify the chip is by device ID, and that seems correct in your OP, assumingy read with Uniflash. Then it's up to the software to choose programming parameters. If it's possible to read and print the device ID with AWDFLASH, you could verify if it's read correctly …

I would try Uniflash; if nothing else it should report the chip's information. You can also find out more by peeling the sticker back and Googling the part number you'll find underneath. I do know that the PCChips M507 comes with an EPROM rather than an EEPROM so, on that motherboard, you cannot …

Definitely there is something wrong with the chip as the taylored awdflash version recognise it as 12v chip, not 5V. AT29C10A is 5V only. Guess I need to buy a compatible chip. Any suggestion to be 100% safe? The only way the software could identify the chip is by device ID, and that seems correct …

Also, check that the original chip in the GA-586DX is a 5V one aswell. There are low voltage versions of 29 series EEPROMs, that I've seen in computer mobos a few times. If you try to access/program a 5V chip with say 3,3V, you might experience symptoms like what you describe. Both chips are 5V The …

For hotflashing two things are relevant: - the EEPROM needs to be supported by Uniflash and the donor board - the 'donor' board you flash on needs tp support Uniflash Apart from that, any differences between boards is irrelvant. If you are getting data verification errors, either the EEPROM is dead …

Sorry guys, it is ga-586dx As far as I can tell it is perfectly compatible with Uniflash but I did not use it to update the board. I used it to hotflash a m577, but did used a regular awdflash program. This time I used aflash and awdflah as well, but both hangs (aflash crash and reboots the system …
