Description Jeremy Katz 2000-08-07 02:29:36 EDT
(Note: this is actually Xconfigurator 4.3.40 instead of the version shipped
in pinstripe)

Xconfigurator is only detecting 1 out of 2.5 megs of video memory on a
Neomagic NM2160 (MagicGraph 128XD).  lspci -vv gives:

00:08.0 VGA compatible controller: Neomagic Corporation NM2160 [MagicGraph
128XD] (rev 01) (prog-if 00 [VGA])
        Subsystem: Sony Corporation MagicGraph 128XD
        Control: I/O+ Mem+ BusMaster- SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR- FastB2B-
        Status: Cap- 66Mhz- UDF- FastB2B+ ParErr- DEVSEL=medium >TAbort-
<TAbort- <MAbort- >SERR- <PERR-
        Interrupt: pin A routed to IRQ 9
        Region 0: Memory at fd000000 (32-bit, prefetchable)
        Region 1: Memory at fea00000 (32-bit, non-prefetchable)
        Region 2: Memory at fed00000 (32-bit, non-prefetchable)

Not a major bug since you can just select 2 megs, but it could confuse
people who don't really know much about their hardware
Comment 1 Trond Eivind Glomsrxd 2000-08-07 09:50:45 EDT
The VESA BIOS call in kudzu returns 1 MB (just as any NVIDIA card returns 4 MB)
- sorry, can't fix.
