FDPP gets confused about boot drive

[andrewbird]

Booting the same disk configuration under FreeDOS and FDPP gives different results. On FreeDOS the boot proceeds as expected, on FDPP it can't find the files referenced in config.sys or autoexec.bat itself.

FreeDOS 1.20

FDPP from git

I've attached the installation files
test-imagedir.tar.gz

Run from dosemu build directory as

bin/dosemu.bin -n -f test-imagedir/dosemu.conf -D+dRW -o test.log --Fimagedir test-imagedir

Firstly with your fdppkrnl.sys in test-imagedir/dXXXXs/c then replace that with kernel.sys from FreeDOS 1.20

How about using the full path to emufs.sys?

[andrewbird]

Yes, but that's a symptom. It can't find autoexec.bat and lands on the D: drive afterwards.

Try fdconfig.sys instead of config.sys

[andrewbird]

Yes renaming config.sys to fdconfig.sys worked, why?

[stsp]

The fdpp boot procedure differs a lot from
all other boot procedures.
dosemu2 looks for different files for fdpp
(fdconfig.sys, command.com), and points fdpp
to them. So the bug is not here, but in dosemu2.
I'll look at what happens.

[stsp]

This is now fixed.
The problem was the presence of a hdimage,
for which I assumed the presence of all needed
files (because of the inability to look inside).
If that hurts, I stopped doing so.

That's looking a lot better thanks

Thanks for taking care of this.
