TBT Steve, I no longer have the cards, so I never looked.

I wasn't aware that it could be turned off and still boot. I'll have to check that on my box next week, thanks. >The >Linux kernel does this pretty well anyway - it'll just list unknown >cards as "unknown vendor" / "unknown device" or similar, but should >still set up address regions for those cards. (I know it does this with >the Mesa cards, for example) At the time, booting bdi-4.3something, there was zero mention of any such devices in the dmesg or lspci outputs. Completely invisible until you found its magic address and tickled it. The cards I had, were a slightly earlier version that had the 82c55 chips mounted vertically, with the 34 pin headers also vertical, and all the cables could be simply taken directly out a missing card cover opening on the back. Now the 34 pin headers are along the top edge of the card & must be folded to point them out of the back of the box. Much messier IMO. If you poke around on that site, there is a pix of the cards I had, but the link to the full page then has the newer card in its pix. >There are only minor differences between the two drivers, but one or the >other should work with just about any 8255-based card (or register >compatible ones) with minor changes. > >- Steve Thanks Steve, here I had thought this card had fallen off the table and been swept up with the garbage. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
