BIOS Updates forum

I have a s7ax mainboard manufactured by DCS. I've been looking for its Flash BIOS for a long time now. The link given on this site and on some other sites as well for the DCS website does not work. I've tried it many times but without a success.
Website: http://dcs.sertek.com.tw/s7ax_bios_history.htm (Commate S7AX)
Above is the link given on Wimsbios website.
Also checked the commate S7AX BIOS but it doesn't work either.

An archived copy is here:

A search for the BIOS names led to here:

(this will get you as far as version 30a)

I have Bios 3.1 if you're interested in :

S7AX Ver:3.1

Nice! Did you download it before the site disappeared?

I have that one too

Please do send me this .bin file onthe following e-mail address zeens_78@hotmail.com

Thanx,
Desvidanya

I've uploaded it to http://rainbow.host.sk/myfiles/Taiwan%2 ... er%20S7AX/

Thanx Rainbow for the flash files but this .bin did not work either. The error is the same "checksum error".

I am not sure what that error means, it is the same with all the S7AX .bin files i have tried but there is a number mentioned after that which is different for all .bin files i used.

Any suggestions???

What checksum error? You mean "CMOS checksum error" after reboot?

I use AWDFLASH.EXE for the update of BIOS.
First, it asks me to identify the source file i.e in this instance s7ax31.bin.
After that it asks me if i want a back up of the old flash file.
After backing up the file it says at the bottom "Unknown Falsh Type" and in the middle of the screen it shows "Error Checksum : 905FH".

The flash file is not updated.

Check jumper settings and use another flasher - another Awdflash version or UniFlash http://www.pppr.sk/rainbow/programs.html#UniFlash

I used the 3.1 Bios without problems in the two board I bought for friends .
I used Uniflash to flash the Bios

@Denniss
Hello Denniss
I have an old Commate s7ax mainboard with the bios version 3.0. But it doesn´t work with Windows 2000 sp4.
So I´m searching for the bios version 3.1, but I can find it to download and Tcommate doesn´t support it any more.
So I hope you could send this bios file to my e-mail address, if you still have this file.

Greetings from Germany
