I bought one of these XT-CF Eco Lite XTIDE cards a while ago and tried it on my PC XT. It currently runs with the XTIDE Universal BIOS (XT) v2.0.0 beta 3.

It booted fine but when having massive read and write operations going on, it would corrupt and a dir would return a list of files with random characters as the names. Recently, I took it out again and tried it on my Tandy 1200, which is an rebranded Tandon XT clone. The XT-CF card would not recognize the CF card plugged in. It hung for a few seconds and then continued to boot from the floppy disk. On the screen, it shows the following:
Code:
Master at 300h: not found
Slave at 300h: not found
Booting C>>C
Error 40h!
Booting A>>A

After booting into DOS, running FDISK will return an error message saying there's no fixed disk. However, when I was trying this XT-CF card on a Pentium III machine, the CF card was correctly recognized and it booted into DOS without any problem. It shows:
Code:
Master at 300h: CF Card
Slave at 300h: not found
Booting C>>C

I have tried different versions of the BIOS ROM but they did not make any difference. Due to the lack of bypass capacitors, I added a 0.1uF cap for each chip, just in case. Oh btw, I have another XTIDE card which runs perfectly fine on my Tandy. Any thoughts?
