Unfortunately I'm giving up on this card; it must have hidden damage.

Thanks for the ideas. The card has 4 different discrete oscillators so I doubt it relies on OSC? I can check the pin. The FCC ID is EXM5RSVGAV4. I already have a V20 in the mail, so I can try it when I get it. Other cards worked in the 8 bit slots. I tried the VGA card in a 16 bit slot in a 386 and …

I got a hold of a functioning (mostly) Packard Bell Force SX20 386 and tried the card in there. Still no video output. The card doesn't seem completely dead, because if I leave integrated video enabled/connected on either machine, but install the ATI card, I get garbled text output from the …

I tried an off-brand 2GB sdcard and had the same problems. I am using a Leading Edge Model D DC-2010E with Phoenix BIOS 3.00; documented working here: https://forum.vcfed.org/index.php?threads/leading-edge-model-d-and-the-xtide.23849/#post-311689. It shipped as a fixed-disk machine. I have the …

I would recommend this process: I followed this process exactly. With soft reboots between steps, it gets to "Starting MS-DOS" and hangs. If you soft reboot to a floppy, command.com has disappeared from C:. It seems clear there is some kind of corruption happening. With hard reboots between steps, …

I used fdisk to change the type to 06h. Booted, formatted, copied, sys’d, and ran fdisk /mbr. On hard reboot the partitions are now gone. It seems like the LBA FAT16 is on the list of partition types the IDE2SD likes, but the CHS FAT16 is not. Although it was initially accessible before I ran fdisk …

Updated my comment to clarify that I created an msdos partition table. You are suggesting I should not create the partition in gparted at all? Above, that was what we had to do to prevent the IDE2SD adapter from wiping the partition table, but I can try it again.

I do get the XT-IDE splash screen. I am using the build for XT with the 4 options across the top. I went through this process: - New cable (80 pin this time) - Use DD to wipe beginning of sdcard - Create msdos partition table in Gparted - Create 1024MB FAT16 primary partition in GParted, cylinder …

I have been using R625. I'm going to guess the problem is the CHS addressing. LBA on the Windows 98 machine works fine. I could try a 2GB sdcard instead of the 32GB I was using, if that would make a difference.

Thanks for the tips. Unfortunately I think this story has a sad end. I used GParted Live to create a 16MB FAT16 partition and nothing else on the card. Booted it up on the XT: - All versions of DOS can see the partition! Great. - DOS 2 will not format it; not a DOS partition - DOS 3.31 will format …

So, I am unable to get any of these partitions to boot, although I can see them and use them. I think the adapters will neither read nor write a partition table that they don't like. What they like are standard FAT32 and NTFS partitions without MBR nonsense. I created a FAT16 partition via USB on a …

I'm posting this so nobody else wastes six hours of their life. I have an XT-IDE rev 04 (c) I'm using with an XT-class machine, a Leading Edge Model D with an Intel 8088 and Phoenix BIOS 3.0. I wanted to use micro sdcards instead of the obsolete CF format. I bought an sdcard adapter in a tray off …

Add an MDA/hercules card & monitor to the system so you can switch to the mda monitor and see what's going on. The Leading Edge Model D has built-in Hercules so I did try that and get the garbled screen. I didn’t try it in CGA mode with a CGA monitor yet. Is there some special trick to disable the …

I'm 99% sure the bus mouse port is round and goes between the two dsubs. If I run the configuration utility without the card installed, it won't start because it can't detect the card. If I install the card, I get garbled video (or none, if I disable onboard video), so I can't see what I'm doing to …

ATI VGA Wonder-16 not working in 8088
Posted on 2023-08-07, 15:26
I got a hold of an ATI VGA Wonder-16. It's labeled as such on the PCB, but it's a 1024 OEM edition so it's missing the bus mouse port. It has MDA and VGA connectors and no jumpers that I can see. The BIOS is labelled VGA 1024 V4-1.01. I put it in my Leading Edge Model D 8088, connected it to a …
