Just a quick note to say that I've updated my EPIA howto to include a little section for the brave on enabling the onboard VGA.
This is based on Sone Takeshi's work.
Thanks to Andrew Ip for committing the update to CVS.
Hi Mark, Thank you for your work.
Perhaps everyone already forgets about it, but I was asked by Ron for a HOWTO on EPIA+VGA. I started it, but it isn't finished. (I was fiddling with BOOT_IDE etc to include in my documentation...) Now that your HOWTO covers VGA, everything is OK.
Some points...
- Line 37-40: NOTE: At present, the epia can be booted with a serial console. Power management to turn off the power is not available, neither is the video bios. Memeory is currenly hard coded to report 64M - you must have at least this much memory.
You can use video console once VGA is enabled (option VIDEO_CONSOLE=1). It isn't very useful however, since VGA initialization is almost at the end of LinuxBIOS execution. Memory configuration is also fixed already.
- Line 364-367: 0 - Disable Framebuffer 1 - 1 Mbyte 2 - 2 Mbytes 8 - 8 Mbytes
This is incorrect. Valid values are 2, 4, and 8 (MB). To disable framebuffer, remove the option HAVE_FRAMEBUFFER.
Also, now I use folowing lines in the config for the VGA BIOS image to be patched in the romimage: option ZKERNEL_START=0xfffc0000 option VGABIOS_START=0xfffe0000 addaction romimage dd if=/path/to/vgabios.bin of=romimage bs=65536 \ seek=2 conv=sync conv=notrunc This way you don't have to handcraft the vga+eb payload.
