Hey all!
A couple of weeks ago I posted this: 486 VLB motherboard questions
Unfortunately after putting all jumpers were they go, the system won't post and there is no video signal from the VLB video card.
I got a POST card. There are no error beeps, either with my old internal speaker that I hooked up nor through the POST card's speaker (wired internally with the supplied cable). I have a USB keyboard connected to a USB-PS/2 adapter hooked up to a mini-DIN to DIN adapter. They keyboard LEDs do not light up. The POST card bank of 8 LEDS have 6 illuminated: -12v, +12v, +5v, CLK, IRDY and FRAME. The +3.3v and RESET aren't and I'm guessing it's normal since this board does not have 3.3v circuits and the RESET lights up when pressing the reset button. The processor is warm so I am guessing power delivery is ok. Also the CDROM unit spins and its power LED light up.
The POST error code is 13. According to the BIOS Central website, the error means:
System-interrupt vectors initialized
However that is for BIOSes prior to April 1990 and my AMIBIOS chip reads: 486DX ISA BIOS 1993 AA9361361. According to the POST card manual, code 13 means:
The video display has been disabled. Port B has been initialized. Next initialize the chipset.
In any case, if that IS the error, what does it mean? Why can't the motherboard continue to the next check? Could it be a faulty video card?
