I have a pair of IBM Thinkpad 755CX notebooks that I really need to get
running -STABLE correctly. The issues are with the video. As you may
recall, this unit uses the WD90C24 vga chip and has 1MB of vid RAM. On
power-up, it is in 640x480 mode, with a black border all around the screen.
It is capable of running 800x600, and to make it do so, you run a DOS
command. I've trompted my way through list archives of all sorts, and
have accomplished all of this now:
1. Built a tiny DOS partition to boot from.
2. Built a nice FreeBSD 4.7-STABLE partition.
3. Put ps2.exe (the utility) and bsdboot.exe in DOS partition
4. Built /kernel with baked-in path to root at ad0s2a
5. Copied /kernel into DOS partition.
6. Boot DOS, autoexec.bat runs:
ps2 MODE3X on
bsdboot /kernel
7. FreeBSD is up and running, except that sysconsoles are all 100x37,
even though BSD runs them as 80x25, jumbling up the screen.
8. Installed XFree86 version 3 (vers 4 doesn't support the WD90C24 chip)
9. Hacked /etc/XF86config to run with this chip and at 800x600 (works!)
Now, I really want the sysconsoles to look good, too. Vidcontrol(1) states:
The following command will set-up a 100x37 raster text mode (useful for
some LCD models):
vidcontrol -g 100x37 VESA_800x600
...and that's just exactly what I want to do. I added the SC_PIXEL_MODE
option to the kernel config (built,reboot, etc), and vidcontrol says
that it can't switch device into raster mode. So, I figure I need to
add the VESA option to the kernel config (b,r,e), and when I do, I get a
page fault in kernel mode on boot. I get it when I try to kldload the
vesa.ko module when VESA isn't in the kernel, too. I have symbols and
DDB in the kernel, but the error message doesn't seem to incriminate
anything that's display-related.
Perhaps the WD90C24 isn't supported any more? Is there a CMOS setting
that creating a I/O memory conflict? Am I just wasting my time?
Thanks in advance,
-Les
