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 :-(.) --ward > Date: Thu, 17 Sep 1998 11:41:08 +0200 (MET DST) > From: Jakub Jelinek > To: ultralinux@vger.rutgers.edu > Subject: Floppy on some UltraAX/UltraAXi boxes > > Hi! > > Just to let you know, on some UltraAX/AXi boxes the single floppy drive you > have is unit 1 and not 0 (B: and not A: in DOS terms).
