Re: Floppy on some UltraAX/UltraAXi boxes

Jakub,

I also tested on Ultra30 too and UltraPenguin maps the floppy as /dev/fd1
or B: in mtools. I tested with PC style "twisted (pin10-16 crossed)"
cable but the system did not recognized. It will be easier for end user
to figure out if it is /dev/fd0. Probably just simbolically link it
to /dev/fd0.

Just to let you all know that this feature exists on all UltraSPARC
systems I tested including AX/AXi and Sun PCI Ultras (not tested on
SBus based ones).

BTW, I felt Xsun24 slower than I expected on a Creator3D FFB so I
did a Xmark/x11perf test. The result seemed to be ok. Obviously Text 
can be accelerated. Of course, this card is for 3D performance and X11perf
is for 2D only. Here is what I got:

Sun Ultra30 Creator3D, 250MHz UltraSPARC II, 128MB RAM, 4.3GBN UWSCSI
OS: UltraPenguin 1.0.9 with kernel 2.1.125
Xserver: Xsun24
Test Resolution: 1280x1024x24bit
Xmark: 13.00051
Xspeed: 
   Graphics :  203192
       Text :  606097
    Windows :  129866

FYR: SGI Onyx RE-2 with IRIX 5.3 xspeed:
   Graphics :   77300
       Text :  267100
    Windows :   20900
(Of course RE-2 is not for 2D either :-(.)
