Hi out there,
i'm running Kernel 2.1.109 + 109ac2 + devfs on my test box here. The framebuffer device is a S3 Virge. I tried allready a few modes (600x640 and 800x600 with 8, 15 and 16 bit colordepth). I calculated the numbers for "vga=" as follows:
hex2dec( <number from linux/Documentation/fb/vesafb.txt> + 0x200 );
So the decimal numbers are e.g. 788 (0x314) for 800x600 with 16 bit colors or 769 (0x301) for 640x480 with 8 bit colors. I get all the time a message like "you passed an undefined mode." - but the debuging message of "vga=ask" tells me the it dedected my card as a VESA VGA Card (what is right).
If I read the code in linux/arch/i386/boot/video.S right (the last time i coded assembler is few years ago - and it was a Borland ASM which is a bit diffrent :-) it gives me this message too if I spezify a non-text-mode. This can't be sensefull since this *is* a framebuffer device and not just a text console!
So what do I wrong? How can i put my box into the VESA mode so I can see the boot logo? What's the sense of live? And why does my beard grow that fast? (I'm allready happy if someone could answer the first two questions in this paragraph :-).
Oh - that's my Console driver configuration:
[*] VGA text console [*] Video mode selection support [*] Support for frame buffer devices (EXPERIMENTAL) <*> VGA chipset support (text only) [*] VESA VGA graphics console < > MDA dual-headed support < > Virtual Frame Buffer support (ONLY FOR TESTING!) [ ] Advanced low level driver options
happy hacking, clifford
PS: IMHO devfs should become part of the official kernel asap. It's one of the most usefull drivers I know and it makes my live much easier!
