Hi Marc,

I gave it a go, it now looks differend, yet it still fails at the end:

Boot sector
...Linux found
..........................................4!
Press key

(number of dots in the longest line may differ from actual)

According to boot_err.h file, the error code 4 means ERR_BAD_SYSTEM

I looked into hd.bin image. It does seem to have correct minix fs with=20
/linux file of size 49778 bytes and /bin/init (instead of /sbin/init)=20
among other files and directories.

Good news with Amstrad PC 2086, I managed to fix its keyboard, it just=20
needed a good scrub. Now I can boot FreeDOS from a CF card and start=20
things like OpenGEM and alike.

Cheers,
Paul
