Came to put my $0.02 into this thread. I got one of these a long long time ago from a scrap pile, was digging through my basement earlier in the week and happened upon it in a box. Rather, I happened upon it months ago, but really only got around to messing with it this past week. Image below is …

Short version: I got my XT-IDE BIOS working in a 27256 filled with 2x16k images, installed in a 3C509 B . Long version: OK, here's what I've learned so far. I have a 3C509B-Combo - the important thing here is that I have a 3C509B not an older 3C509. I have an old Atmel 27C256R (120ns) EPROM - 32Kx8 …

So I got it in today, crazy fast shipping from Arizona as mentioned in the last post. I'm genuinely amazed how quickly it made it here! I wasn't expecting it for another few days at least. I got it out of the box and got to work cleaning the exterior. it's MUCH cleaner now. it was all sorts of …

Kodiak were a wholly-owned subsidiary of SEEQ Technology , a semiconductor designer and manufacturer of data comms products - https://web.archive.org/web/19961114191916/http://seeq.com/ -(bought by LSI late 90s), so possibly Kodiak products may be based on SEEQ ICs / generic drivers?

pulling my hair out trying to figure out why the XT-IDE UB ROM when shoved into my 3C509B in my 386 will find the second IDE disk in my system, but not give any drive letters to the three partitions. yet, with the same ROM in an XT-IDE card, will magically just work with nothign else changed.

Yeah, looks like it's set up in a way to take x MB from system RAM at boot time somehow to act as VRAM over the PCI bus. seems like it'd be a rather slow 2D card.

for the old ISA cards they did use japanese caps quite a bit, got an SB16 CT2290 with mostly chemicon SMG and an AWE64 with nichicon VR on it, though especially towards the sblive era they were mixing in a lot of stuff like wincap as you said. with x-fi i've not seen any japanese caps at all, …

audio issues with these cards can have other causes as well, particularily when putting them into old VIA chipset machines and such. heck, keep in mind that some games are simply broken or need a very specific card to work. i once removed the caps in that spot on a 2zs and they all measured well …

Hi, I also have the same board :-) I can't get the sucker to boot of any USB though.. You need to think outside the box to get this board to boot off a flashdrive, it's a bit picky. CD-ROM boot is preferred for it. for USB, you need to basically dd an ISO onto a flash drive instead of using rufus …

As for the X3x, the problematic one is the X31/32 (but mostly the 31) - it’s definitely a mechanical issue, but it has more to do with having 4 large BGA chips on the board with no bracing - the Pentium-M CPU, Northbridge and Radeon M6 on one side, and the Intel ICH4 southbridge on the bottom.
