Hello I have a VGA card marked FCC ID:KJDKEN-CL542XVL1 and on solder side CL5426VL1 and with a marking on a sticker VL/CL5428 CIRRUS LOGIC 1/2MB that has no bios chip and no RAM DIL chips .
Did search Google for it and the only thing showing the card is https://ru.pc-history.com/cvlvga-542-xvl-vesa.html. VGA Museum has no data as far as I searched.
I want to complete it - mainly to get the BIOS download . So please I need a help.

You will have to use a generic Cirrus Logic 5429 bios You can get from here https://www.vgamuseum.info/index.php/cpu/item … logic-cl-gd5429

You will also need an eprom programmer and a 27c256 eprom or eeprom.

Thank you Imperious for the reply I thought the 29 version will not work. Meanwhile I've obtained CL-GD5907-20DC-1.00D eeprom . Reading it with TL866II, it is for CL-GD5440 with a date: 08/07/95 so I think it will not match.
