Flashing now works again.
Hack to get Windows 95 to work properly (MODULE_WIN95_CMOS_HACK included for 386 builds by default).
Edited makefile to produce large 386 build.
Fixed recovery time for QDI Vision VLB-IDE controllers.
No more warnings with Nasm 2.13.xx and later.
File dialog now properly restores default drive when file selection is cancelled.

     169; to signal to DOS that we will handle this ourselves. However, this only works on DOS 5+ so on older DOS versions we instead try to filter out
     170; the "other" logical drive (the one that isn't the current drive) during drive enumeration so the user can't select the "phantom" drive to begin with.
     171; This will have the somewhat strange effect of having a drive B: but no drive A: if B: happens to be the current logical floppy drive.
