Does Xvesa require networking support? If so, why?

I have no idea how to use a USB mouse in linux but will try ours if
someone explains how. I did not try the camera because you said
usb-storage did not work right, but I will try tomorrow if you want.

Okay, I will install the svgalib package from SW91. I really need
to get a few computers put back together first and fix a major scsi
problem (three devices, all with problems, maybe caused by one bad

Yes for seejpeg. I don't know about zgv. Why is the static version not
working with the 2.4.31 kernel?

So the problem has nothing to do with how you compiled the kernel.

I goofed, I meant ghostscript 8.50 not lynx. It compiled for X okay.

Not if I can get svgalib/zgv working so I can check that the photos are
really there and not corrupted before I delete them from the camera.

The minimal kernel will be handy if it can be put onto a 2-floppy BL3
set to use on other people's computers. Does your kernel mount DOS and
Windows file systems?
I will work on the svgalib upgrade.
And try 2.2.26 kernel with usb-storage devices (and maybe a mouse, but it
is simpler to use the PS/2 adaptor).
