Description Stelian Pop 2001-01-12 16:07:44 UTC
Anaconda misdetects the amount of memory present on my video card: 256KB
instead of 8MB.

Assigning to a developer.

Comment 2 Brent Fox 2001-01-17 23:16:40 UTC
Can you run ddcprobe and send me the output?

Comment 3 Stelian Pop 2001-01-17 23:23:43 UTC
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.

Comment 5 Stelian Pop 2001-01-18 12:19:58 UTC
Here it comes, the output of ddcprobe.

This is *not* a laptop.

You seem to be right, the card reports 127*64...

Great!  This issue has already been fixed.  Resolving as rawhide.
