I decided to test something and bought an ide to cf adapter and a 128mb cf card for my 1993 ibm ps/1. I havent copied the ps/1 software yet off old hdd (need 2mb floppies...not sure where to find those) so installed dos 6.22. The cf card is detected in bios, dos sees and installs to it but when it reboots. Goes to black screen with the letter "j" in the upper left corner. Ive tried to format and reinstall dos several times but nothing changes. I can put in boot disk and see files on the c drive but I cant get past the j screen. Anyone have an issue like this or is this ibm notbable to have any other type of hard disk besides regular type?
