[RESOLVED] "Winbond" HD MF board

I put "Winbond" in quotes because although it uses Winbond chips, Windbond Corp. adamantly denies having made it--"We don't make boards, we just sell chips." But Windoze95 identifies it as a "Winbond VL-IDE board" and correctly identifies the chip used in it. Say what?
Anyhow the thing works fine in this computer ... it's a VESA-bus Aunt Tique, dontcha know, but it handles my three hard drives and CDR drive no sweat.
What I need to know: It is a MF board, containing LPT, COM1/2 and game controller. I have figured out how to disable the game controller (because it argues with the controller on my sound card) ... but I can't for the life of me discern the logic behind the jumpers for controlling the other I/O ports. Has anyone had experience with this Beast in the past and can point me in the proper direction? Thanks.

I have 'played' with a number of the VLB boards with the Winbond chips and ended up pulling hair out in the process...

Is there an FCC ID on the board? If so, use the drivers link from Windrivers home page to search for the company. You may be able to find the manufacturer. I know one of the boards I worked with was made by Promise Technologies and they have extensive documentation on their site.

Are there any other numbers, stickers, labels, etc. on the board that may help ID the board? What kind of connectors are on the board? How many jumpers are there and how are they labeled?

If your dual IDE VLB I/O card is the very common PTI-255W, (both model # and FCC#), I have both manuals and drivers (DOS & W3.1). Give a shout if I can help. Bye.
