hi friend, thank u for u help.
I have get some progress on my problem.
first i have successfully install microwin to my system ( enable X11 , disable frame buffer) and run demo in X mode.
but as for framebuffer mode ( enable fb in microwin's config)i still can not use.
I have found in standard installation, linuxconf and menuconfig
are all ignored by system. so i install redhat 7.1 again.
choose linuxconf in application->system, choose kernel in development.
well, i have those files now.
but the problem is if i use linuxconf to config vga mode to 0x311 in lilo,
it will notice me that this mode not support when booting.
I think i should rebuild kernel first to create framebuffer device in /dev.
Referring to http://www.linuxdoc.org/HOWTO/Framebuffer-HOWTO.html, i run
make menuconfig in /usr/src/linux, but in the Console Drivers menu,
I only have two options ( VGA TEXT CONSOLE and VIDEO SELECTION SUPPORT)
miss SUPPORT FOR FRAME BUFFER DEVICES,VESA VGA GRAPHIC CONSOLE, ADVANCED LOW LEVEL DRIVERS,
AND SELECT MONI.2BPP,4BPP....
why this happen, is there error during my operation?
could u or any one help me ?
Regards
Daniel Wang
