Actually, Christine, by that time the system’s already in protected mode. We
display that “Press escape to stop loading blah…” from inside our drivers’
DriverEntry. We map the video memory at B8000, we map the Bios Data Area to
pick up the screen width and height, and we display the message by writing
characters and attributes to the video memory.
Alberto.

While Win2k is booting? When it is still in “text mode”?
Try embedding some assembler and use the int 10h/16h functions.
The BIOS for our RAID card is responsible for downloading new firmware, and
also responsible for getting as far as loading the driver during boot. We
call the int 10h video functions and int 16h keyboard functions to
communicate with the user.
HTH, and Harmony,
