I have put a freshly purchased XT-CF-lite v4.1 in my IBM 5155.
The CF card I'm using is a 512 MB Sandisk that has been formatted for FAT.
I uploaded the latest version of the XT IDE universal BIOS (tried both the XT and XTL build) to the 28C64 ROM (with a MiniPro) and set the ROM address jumpers to D0000 as I gather from the description that's the default address configured in the ROM code.
Based on some articles I found, I also tried setting it to C0000 and CA000, all with the same result:
When the machine passed the RAM check, it shows on screen a message with the address that is selected with the jumpers and then "ERROR" and I need to press F1 to continue.
Then it continues to boot from floppy.
It does not show anything from XT IDE universal bios and I also cannot access the card.
I've taken out all the logic chips one by one and tested them with a chip tester, just to make sure that is not the problem.
The ROM can also be read from and written to with a MiniPro, so that doesn't seem to be the problem either.
Does anyone know what is going wrong?
