Misdetection of MACH64 video RAM
Last modified: 2007-04-18 12:30:40 EDT
Anaconda misdetects the amount of memory present on my video card: 256KB
instead of 8MB.

Can you run ddcprobe and send me the output?
Will send you this tomorow morning (Europe TZ), it was a test machine at work,
don't have access to it right now.
Is this a laptop? I'm curious. I've seen this behavior on other Mach64's, but
they were laptops. My guess is that the memory that the card is returning is
understating what it should be. Usually, an 8 Meg card will return results like
128 x 64 for it's memory, which is 8192 kb, or 8 Megs. However, on some Mach
64's and also some ATI's, the card will report 127 x 64, which is 64k less than
we expected. I've already added code to check for this condition, so this issue
may already be resolved, but I need the output of ddcprobe to make sure.
Here it comes, the output of ddcprobe.
This is *not* a laptop.
You seem to be right, the card reports 127*64...
