Message:

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.
