Re: Freebios1 STPC Elite development board changes attached

[Fathi BOUDRA]

no, i use set these options :
VGA_CONSOLE = 0
PC_KEYBOARD = 0

this is ok, the same problem of peter fox. I used the modified timer.c for 
filo (don't use rdtsc in filo because it's a 486) and now it works.

if someone need it, i join it.
