Dear all,

I am looking for a manual for above mentioned card.
I could just find sth for VLB / PCI versions but not for the ISA version.

Someone out there with more luck? Thanks a lot

The jumper is most likely selecting between color and B/W output.

I tried them out. No B/W. Having one disabled leads to fully broken picture no matter which video mode. It even seems then sensitive to isa bus speed as it increases the pixel errors. Having this one enabled all ok. The other switch no idea since no noticeable change.

The only jumper seems to be factory default. As soon as I change it the system won’t boot

Hi, my SPEA Mercury has a defect (very hot) BIOS IC. Does anyone have the bios file?
