Hi,

I have a PCI ATI Mach64 (2Mb VRAM) and I am having no luck getting XFree86
to work with the XF86_Mach64 driver.  I cannot even describe what it is I
am seeing when I startup the X server.  It's just a black & white screen of
garbage.  I've tried the XF86_SVGA driver and that one works fine ... for
the standard SVGA settings.  I cannot use any setting that requires more
than 1Mb of video memory (as the SVGA driver says) without the display
going wacky.

Is anybody out there using the XF86_Mach64 driver with a PCI ATI Mach64?  I
am using the version of XFree86 that comes with FreeBSD 2.0.5 (I don't know
the exact version at the moment).  Here are a few more of my system specs
just in case ...

P166, 32Mb RAM, SB16-SCSI2 (ISA), SCSI Plextor 4x, SCSI Sony 4x, 2 540Mb
IDE Maxtor, 2.1Gb IDE Western Digital, NEC Multisync XV17+, FreeBSD 2.0.5.

Here are the relevant sections of my XF86Config file ...
