PXAFB command line for standard VGA monitor

[Victor <pfc@xxxxxxxxxxxxxxxxx>]

Hello,

We recently adquired an ARCOM VIPER Board (PXA255) for some
development purposes. It came with FPIF-CRT adaptor to use an external
standard VGA monitor ("Converts the VIPER-Lite flat panel output to a
standard analog RGB VGA signal for use with a regular monitor"). I've
having lots of problems to make my kernel display anything on our
computer monitors (15-17-22'' TFT monitors). I always end getting an
about "out-of-sync" or something like that.

Arcom Viper's manual just talks about configuring pxafb with
mode:640x480-16 for VGA monitors. Ive tried that, and some more
options without any result.

Is there a way to calculate what parameters do i need to pass to
video=pxafb to make the kernel fb work on an standard VGA monitor?

Thanks.
