It seems, something is broken with the Floppy Disk support.
I am no more able to boot UCSD p-System disks. P-Code card is on.
Will check also other disks (Assembler/Basic) and ti99_xx driver.

OK, it seems only boot disk problem exist, if the P-Code card is activated.
Without the P-Code card, I can boot disks.

The problem not exist with the official MESS 0.134 release.
