Hi all,

I have a small problem with my IPC P5 laptop.
I've installed Linux 2.0.0 (Slackware96) and XFree 3.2 on it,
and it runs off the LCD screen fine, but I haven't been able to
configure it to run an external CRT screen.

The problem is that it doesn't have any hardware method of switch
to the external display (that I know of anyway, I haven't got any
manuals for it). The only way to switch is to run some .com programs
that come on a utility disk. However, they don't run under linux
(of course), and as they use a non-standard BIOS, they won't work
under dosemu either :-(

So, does anyone know of a way to switch between the internal and
external displays while in Linux? Even just the BIOS calls would
do, so I could just implement linux versions of the .com programs.

As an alternative, is it possible to boot linux (using something
like LOADLIN) from a DOS floppy, without resetting the hardware.
At least then I'd have some control of the display, even if I did
have to reboot each time I wanted to change it.

Thanks in advance,

Richard

ps: Email replies, and I'll post a summary if we come up with a
    solution.
