I found out that 64-bit int type is long long.

as for the replacement for biosdisk.c, I am running into troubles.  it 
seems everything revolves around the Disk Packet, which is a structure 
of size 16 bytes.

the problem is, the go32 libraries seem (?) to only allow allocation and 
use of 1 block of dos memory at a time.  I need 2: 1 for the Disk 
Packet, and 1 for the disk buffer the Disk Packet points to...

so what do I do now?

it compiles now, but that's about it.  testing reveals it doesn't work. 
  However, I do know that the interrupts themselves do work.  it's my code.
