BIOS Updates forum

Got a 6ZX86 board, but without serial/parallel cables. Now I need to find out the pinout of the connectors (not listed in the board's manual) to buy/make suitable cables. Tried Google - no result
Can anyone help?

Thank you

Thank you once again, apple_rom! :) But before making any hardware modificactions I want to clearly understand what I'm doing. So I tried to find the VT82C693A data sheet (I know that there is nothing on VIA's website), but only got some brief data sheets, which obviously weren't very helpful. Does ...

Thank you for your answer. What hardware modifications are exactly needed for 256Mbit memory support? Are there any side effects?

TIA

Fixed the GA-7VA today. De-soldered the BIOS chip with a cheap heat gun (350° C, didn't dare to use the full power). First the chip behaved weird when I put it in my programmer (and I thought I killed the chip), but afterwards everything was OK. Didn't want to heat the flash chip again so I soldered...

Simply flash the most current.

Sorry, didn't know that (and didn't test either ).

What about upgrading to A6?

Ver. E can be found here, for example.
BIOS string: 09/01/2000-693-596-SMC-2A6LGX3KC-00
BIOS signon (or whatever it is called): 6VIA85P Ver:E 09/01/2000

BIOS upgrade to ver. E (as far as I know the latest version available) didn't help - still only half of the RAM size recognized

The mobo mentioned in subject only recognizes half of the Spectek 256MB DIMM (8 chip, P32M648YAC-75A) although VIA 693A northbridge should support 256Mbit RAM chips
BIOS issue?

Did you overclock?

I haven't see any myself, too...

What about other PC components (or any other widely used devices)? Need some 3V flash chips for testing purposes (want to build a 3V adapter for c't flasher), but I don't want to order new chips and then (maybe) burn them.

Atmel AT49F002NT is a 2Mbit 5V-only flash chip.
