I recently found a bug when reading drive C, on some circumstances.
My configuration is
RAM: 2Mb
Hard-disk: 20mb sectors: 17 Head: 4 cylinders:615
Hd-controller: Xebec.
The bug can be found when installing Word 5.5 for DOS, using Xcopy command from drive A to C,when I do zoom out in PC paintbrush for Windows 2.0 or when I launch
pcbrush.exe from plain DOS.
Strangely enough if launch pbrush.exe from DOS and i put "fail" in the general error, return to DOS prompt, and the then I launch the Pbrush.exe from Windows, open an PCX file and do a zoom out, the problem does not apper.
(I don't know if its a problem with the controller emulation or the T1200 bios)
PD: I had to create the partition with Toshiba T3100 (which is an AT machine) because I could not create it from FDISK or debug command either, in any XT machine.
Thanks in advance!
