Very Computer

Hello,

I want to decide what local-bus 486-configuration is oke for Linux with X11.

I'm testing VL-486DX266 systems with 8MB and local bus boards.

System I : This is a 486DX266 with one VL-combo for IDE and VGA.
           The Chipset for the VGA : Cirrus Logic CL-GD5426-80QC-A.

The VL-combo board has jumpers for :

    VESA BUS VGA (enable/disable)
    VESA BUS IDE SPEED : normal/medium/high speed & reserved mode.
    IDE BIOS SELECT (enable/disable & segment address)

System II : This is a 486DX266 with a VL-VGA with Cirrus Logic 5426/28
                               and a FSIOL-PA1 VL-Bus board for IDE.

The boards have jumpers :

   VL-VGA IRQ9 (disable/enable)
          GREEN PC (disable/anable)
          This board has 1 MB (may be updated with 2 MB)

   VL-IDE HDD R/W Speed (600ns/380ns/200ns)

Questions :

1. What's the performance-gain of the local-bus (compared to normal ISA)
   for a WD-Caviar WDAC2250? How can I measure this?

2. X11 does not start.
   This is the information, I have for the VL-Combo board :

The messages I get :

VGA256: Virtual resolution set to 1024x768
Caught signal 11.  Server aborting
giving up.

For the other VL-VGA board with the Cirrus Chipset, the messages are
almost the same. But if in the Xconfig no Chipset is specified, the server
detects the Chipset.

The following message appears :

Cirrus Logic Chipset used, but unknown type.
And the same signal 11 occurs.

Any help greatly appreciated.
Thanks,

Ger
