Undefined video mode number: 312 [VMware]

[Medox]

This appears everytime I run my TC in VMware, in text mode with vga=786. I then press enter and select 33F (640x480 - how I need it) and it works great but when I add vga=33F to isolinux.cfg it switches to some other, even smaller, resolution (too small). How do I solve this?

vga=786 (in decimal) is vga=0x312 (in hexadecimal)

I don't know where you get the vga=33F from, but as a hexadecimal number 33F would need to be written 0x33F

vga=0x312 didn't work, in my case, but vga=0x33F did. Thanks!

p.s. 33F is from the list that appears after pressing enter (see first picture)

Ahm... new problem.
Now I get Undefined video mode number: 33f, in VirtualPC & Qemu...

Any way to use both? So that every soft/pc would get the right video mode (0x33f/786/0x312)

What, VMware doesn't support the standard 640x480? *cough*

And instead of the standard, they have defined their mode to 0x33f aka 831, which on the other hand is *not* valid on any common video bios. You'll need to either use text mode, or find a mode that works everywhere (meaning a standard one that VMware also supports).

[Medox]

so there isn't any "patch" that would do something like:

if 786 ...
else 33f

?

or maybe with some recompiling and other crazy stuff!?

[curaga]

Sorry, no

[Medox]

But who/what generates this video mode message? Isolinux or something else? (sorry if it's a stupid question...)

I have in mind to remove the echo-kinda-something ("Press <ENTER> ...") with vga=786, in this case. Or the other way around... if not 312 then go to 33f instead of showing that press enter bla bla.

It's the linux kernel's framebuffer init. I'm not sure where it is, or whether it's C or asm.
