Hello, I have 5160 clone with two sockets (one for ROM, another, empty for BASIC). I downloaded Turbo XT BIOS 3.1 and selected to include IDE, FDD and BASIC ROMs. Im using two AT28C256 chips and I managed to run pure Turbo XT BIOS but it is showing that there is no BASIC ROM, also IDE and FDD BIOSs seams not to start. Previusly I used IDE XT BIOS on option ROM on LAN card and it was working. When I open ROM images (u18.rom and u19.rom) it seams fine, as I understand first 24KB on U18 is BASIC (3/4 of it) and last 8KB Turbo XT BIOS which works, in U19 last 8KB is 1/4 (first part) of BASIC and Turbo XT BIOS should look for BASIC there. First 24KB on U19 is FDD and IDE. I checked and U19 sockets is getting 5V power and I can read and write AT28C256 for U19. So the question is what could be the problem here?
