Bttv...

I bought one gig of memory today, after which I had a total of 1,3 gigs of ram... anyways, After I enabled highmem support in the kernel, xawtv refused to start saying something about bttv memory allocation failure etc etc... without highmem support everything runs fine except that I am only using 1 gig of the 1,3 gigs of ram I have! What does all this have to do with nvidia? well... highmem support and bttv work together if the NVdriver module hasn't been loaded...

Any thoughts?

Disable highmem support and try the kernel command line option
' mem=1280M ' . Take a look in the man page of bootparam
by entering "man bootparam". It should be possible to write this option
in your boot loader config file.

If this does not work try the following:

Under the kernel config option "high memory support" for compiling
your Linux kernel 2.4.x select "4 G".

And under "user address space size" select "2 G".

"Disable highmem support and try the kernel command line option
' mem=1280M ' "

Didn't work


"Under the kernel config option "high memory support" for compiling
your Linux kernel 2.4.x select "4 G".

And under "user address space size" select "2 G". "

Where can you set the "user address space size"?
I can't seem to find it

I've run "make config", take a look at the last
two lines. It's kernel 2.4.18 on my machine.

It works !!!

Thanks for the help...
