I recently bought a low-tech XT IDE adapter off eBay. No matter what I try I can't seem to get the card to work the way I need. I'm using MS-DOS 2.2, and when the card is installed it refuses to let the computer boot from anything in the floppy Drive. I have no other way of getting information on to the card other windows 10 via a usb adapter. I have managed to get as far as to getting a primary dos partition installed onto the compact flash card, so now the computer will just display "no operating system" and when I put the card into Windows 10 it does not recognize the formatting and refuses to mount the card. I don't know what to do at this point and I'm at my wit's end with it as this would be the only way to enable me to put software on the machine. If I can get it to boot the A drive with the card, I can more than likely figure out something from there. As it sits when the XT IDE ROM is enabled it will allow me to boot into everything except for the floppy disk drive, because when I try to boot the disk drive it just resets the machine over and over until i select something other than the a drive to boot which would be the IBM basic, or the cf card. When I unplug the jumper for the ROM on the XT IDE it completely shuts off the card and does not allowed access to the compact flash, but then the computer boots as if the card were never installed. If someone has successfully installed one of these cards on an IBM 5155 and would have any information that could help it would be greatly appreciated.
