______________________________________________________________________
1. Supported hardware
The current accelerated I128 server supports
o Imagine 128 (I128 with Texas Instruments TVP3025 or IBM528 RAMDAC).
It has been tested with with 4MB of VRAM.
o Imagine 128 Ticket 2 Ride (I128-T2R with IBM526 or 528 RAMDAC). It
has been tested with 4 MB and 8 MB of VRAM and DRAM.
o Imagine 128 Revolution 3D (I128-R3D with IBM526 RAMDAC). It has
been tested with 4 MB, 8 MB, and 16 MB of WRAM or SGRAM.
o Imagine 128 Revolution IV (I128-R4 with SILVERHAMMER RAMDAC). It
has been tested with 32 MB.
2. Features:
o uses linear frame buffer
o Resolutions up to the maximum supported by the card should be
possible.
o 8 bpp, 16 bpp (depth 15 and 16), and 32 bpp (depth 24, sparse) are
supported.
o supports RGB Sync-on-Green
o Makes use of the graphics accelerator.
3. Configuration:
The I128 driver should auto-detect all supported hardware so you
needn't have anything other than the Identifier in the Section
"Device" of the xorg.conf file. When running the xorgcfg or xorgconfig
programs one merely needs to select an I128 card so that the correct
server will be used. One need not and should not specify a RAMDAC,
clockchip or allow the setup program to probe for clocks. The driver
will auto-detect the amount of video ram present.
The following Section "Device" options are supported by the I128
driver:
o Option "Dac6Bit"
Will enable 6-bit DAC support.
o Option "NoAccel"
Will disable all hardware acceleration.
o Option "SyncOnGreen"
Will enable syncing on green for sync-on-green monitors (these are
typically fixed frequency workstation monitors).
4. Mode lines for the Silicon Graphics flat panel display:
o These mode lines are required for use with the T2R4 (Rev 4) and the
Silicon Graphics Flat Panel display.
