I used to believe the same like you... but then why Allegro 3.12 (that uses inp/outp) works and WIP 3.9.32
(inportb/outportb) doesn't work? Personally I've also always used inportb/outportb (more readable), but this time I was
forced to use the others. If they are the same, i.e. inp/outp are like macros that use inportb/outportb, then why old
Allegro works? I've compiled both 3.12 and 3.9.32 with the latest DJGPP packages, just installed, and under the same
platform (Win95 DOS box).

Hummm... Adding delays could be a solution, but then it brings me again to think inp/outp are different from
inportb/outportb; why the first ones need delays, while the others work anyway? Again, Allegro 3.12 does work with my
SB 64 PCI, and it uses inp/outp.
Don't get me wrong, I also hate these "magic" solutions, but this time it seems like it's the way to get it to work on
my computer. Anyway I'll try more hacks, even if I believe the problem is there... If adding delays after
inportb/outportb will work, then it'll be sure they are different from inp/outp.
By the way, is there anyone out there with my same problem? I'm in contact with a guy on ICQ that has the same problem
(i.e. the WIP DOS Soundscape driver doesn't work, while with 3.12 it worked), but with a SB 128 PCI. Anyone else?
