New Radeon 7000 ROM

1
Dear Denis and Group,

There is a new Radeon 7000 ROM available
which fixes 10bit gamma clut problems. It can
be downloaded here.

http://mirror.ati.com/support/drivers/mac/ati-radeon7000-mac-rom-208.html

CopyBits speed is still bad but 10 bit gamma looks fixed.
Merry Christmas and Happy Holidays. Take care,

Doug T.

Here are my cluttest results

FileSharing is on.
WARNING: Virtual Memory (VM) is on. This makes it unsafe to raise
priority to
minimize interrupts. VM uses the hard disk to swap pages of
memory.
Thus any memory access, eg using a Matlab array, may require a
disk
access. Any attempt to access the disk at raised priority will
hang
forever. For this reason, MaxPriority always returns zero when
VM is
on, which is safe but sacrifices the interrupt-reducing benefit
of
Rush. Please use the Memory control panel to turn off Virtual
Memory.
Buy more memory. It's cheap. E.g.

No serial port arbitration.

Dear Doug,

Some time ago you said you had code that would synchronize the
vertical blanking on the two heads of a Radeon card and could
send it to me. It would be really helpful to us to get that.
We're particularly interested in the 9000, but would take
anything you have as a starting point.

Thanks.

David
