The report was probably mine. My Compaq LTE Lite/25c (386SL) runs
linux 0.99.4 fine with all power management functions working.
With more and more people using Unix and OS/2 a notebook
shouldn't rely on DOS utilities or real mode BIOS calls.
Why don't you take a Linux boot/root flop to the store and
give it a try? On my notebook I can even use a hotkey to
get a battery meter window on screen while running Linux.
Get enough memory. Although RAM takes up some power it is
nothing compared to continuously swapping to the hard disk.
As I understood a 387SL stops when not in use (minimizing
power use) and I didn't experience any shorter battery life.
Well worst power consumer is probably the color LCD screen.
Xmono works fine, but I guess the bankswitching routines have
to be rewritten for Compaq SVGA to get 256 colors. :-(
Does anybody have a tech manual?
