So the data technology vlb controller card worked finally. I was getting those weird missing irq? in syschk.exe and I decided to take the unecesarry cards out (GVC nic-2002bt and a suncom gameport controller) and the interrupts and mouse work fine now. I’ll try and avoid unknown brackets with serial …

if one is long enough you could try swapping it into your original card Just tried that and no good. I believe my two acer chipset isa controller cards need the crossed pin ribbon cable, while all my vlb controller cards are straight through. Every card I try has an issue. The vlb cards I can’t …

Small favour to ask. Would you mind dumping the BIOS ROM image? You can do this with a DOS utility called Navrátil System Information (NSSI). Before you do, just enter the CMOS setup and temporarily disable BIOS Shadowing (System ROM shadow) under the Advanced CMOS Setup. Sure will give it a try. …

Okay right. What is 3fc? Shouldn’t I use 3f8/2f8 to designate the com port? Or is this just the hex for flipping the dts ? Well the 25pin is built-in to the card so if I could dig up a db25 to db9 converter that would work for the time being. Hella ugly though. Also found these two Data Technology …

Did that port on the ribbon cable come along with the board or separately? There are two pinouts for those serial headers, basically 1-2-3-4-5-6-7-8-9-10 vs. 1-3-5-7-9-2-4-6-8-10 Not sure, since I have a lot of old stock. I have tried some I/o controller cards where the serial port is on the same …

Concerning the soldered wire, did some cards actually get sold like that with factory patch jobs or were they sold as refurb aftermarket products?

No need to drill anything. Just use some plastic spacers to keep it away from the metal plate. The board is held in place by the ISA cards and the one metal standoff. I mean these things True. That would suffice if I wasn’t the type that is constantly swapping out different video cards. Adding and …
