🚀 go-pugleaf

As a follow-up to my previous post, I have now gotten go32.exe and
debug32.exe to work with my little program that uses INT 13H. I did
so by patching the .exes to let INT 13 pass thru (since I don't have
Turbo C I couldn't recompile from the sources, but I just put a 13h
in place of the 17h in the list of pass-thru interrupt numbers - I
don't need the printer services provided by int17 anyway).
The calls to INT13 work fine except for the "read sector" call which
expects the address of the buffer (where the data should go) in
ES:BX. Data is in fact read from the disk, but appears to finish somewhere
in Nirvana. Setting ES is useless anyway (from what I understand,
there is no way to force the segment registers to be set to specific
values), so I just set BX to point to the address of my buffer. Unfortunately,
the BIOS seems not to care.
Am I completely out of luck with this one?
Thanks for any hints!
