Current FreeDOS fdisk utility (Users)

posted by RayeR Homepage, CZ, 02.02.2021, 07:28

I had to fix some more typing and absolute paths in makefile and was able to add some debug prints. On my SSD fdisk reads labels from this locations:

[SSD]
C: LABEL READ FROM: disk=128, part=0, C=0, H=0, S=0
L: LABEL READ FROM: disk=128, part=1, C=277, H=0, S=0
