Hi!

I have an ALR PowerVEISA 486/25 with Phoenix BIOS Version 1.00.04.
On my machine, the setup program is indeed located at that address.
Furthermore, it can be called (almost) anytime by pressing Ctrl+Alt+Esc.

Btw, I haven't got the slightest idea how they do this. It even works
after loading my German keyboard driver, which remaps INT 9 and INT 16H.
It even works under Windows 3.0 _in a DOS window_. It even works
under OS/2 1.2 in real mode, though sometimes it crashes the system.

Does anybody have the same machine and has figured out how this works?
Somebody at ALR or Phoenix listening?
Just curious...

Harald
