I spent another retro-weekend with my #Toshiba T300 #Pasopia 16.

Now I know that #OpenWATCOM produces 16-bit #DOS executables that run on the old special Toshiba-MS-DOS 2.0.
However, when I tried to run code using the `_bios_disk()` function to directly read #floppy disk sectors, the buffers were not filled correctly.

I wanted to create an image of the 640 KB boot disk by copying it in smaller pieces onto multiple #IBM 360 KB disks.

Well, looks like I need to do some standard PC tests first.
