Thanks Bill and thanks Wolfgang! VGA BIOS is the problem. I use scitechsoft
videoboot to initialize the card. Videoboot is based on scitechsoft x86emu
which could run x86 code on other platforms. Now I successfully initialized
the card and get the framebuffer information. But the monitor still gets NO
SIGNAL through the card.
Serial console shows framebuffer is enabled:
videoboot: Booting PCI video card bus 0, function 0, device 6
aty128fb: Found Intel x86 BIOS ROM Image
aty128fb: Rage128 BIOS located
aty128fb: Rage128 RK PCI [chip rev 0x2] 32M 64-bit SDR SGRAM (2:1)
fb0: ATY Rage128 frame buffer device on Rage128 RK PCI
Some information I get from framebuffer:
id = ATY Rage128
depth = 16
smemlen = 33554432
line_length = 0
FB_TYPE_ = 0
type_aux = 0
FB_VISUAL_ = 3
xpanstep = 8
ypanstep = 1
ywrapstep = 0
mmio_start = bbffc0000d
mmio_len = 8192
accel = 32
xres = 640
yres = 480
xres_virtul = 640
yres_virtul = 480
xoffset = 0
yoffset = 0
bits_per_pixel = 16
