20  The current accelerated I128 server supports
21
22
23  +o  Imagine 128 (I128 with Texas Instruments TVP3025 or IBM528 RAMDAC).
24     It has been tested with with 4MB of VRAM.
25
26  +o  Imagine 128 Ticket 2 Ride (I128-T2R with IBM526 or 528 RAMDAC). It
27     has been tested with 4 MB and 8 MB of VRAM and DRAM.
28
29  +o  Imagine 128 Revolution 3D (I128-R3D with IBM526 RAMDAC).  It has
30     been tested with 4 MB, 8 MB, and 16 MB of WRAM or SGRAM.
31
32  +o  Imagine 128 Revolution IV (I128-R4 with SILVERHAMMER RAMDAC).  It
33     has been tested with 32 MB.

37
38
39  +o  uses linear frame buffer
40
41  +o  Resolutions up to the maximum supported by the card should be
42     possible.
43
44  +o  8 bpp, 16 bpp (depth 15 and 16), and 32 bpp (depth 24, sparse) are
45     supported.
46
47  +o  supports RGB Sync-on-Green
48
49  +o  Makes use of the graphics accelerator.

52  [1m3.  Configuration:[0m
53
54  The I128 driver should auto-detect all supported hardware so you
55  needn't have anything other than the Identifier in the Section
56  "Device" of the xorg.conf file.  When running the xorgcfg or
57  xorgconfig programs one merely needs to select an I128 card so that
58  the correct server will be used.  One need not and should not specify
59  a RAMDAC, clockchip or allow the setup program to probe for clocks.
60  The driver will auto-detect the amount of video ram present.
61
62  The following Section "Device" options are supported by the I128
63  driver:
64
65  +o  Option "Dac6Bit"
66
67     Will enable 6-bit DAC support.
68
69  +o  Option "NoAccel"
70
71     Will disable all hardware acceleration.
72
73  +o  Option "SyncOnGreen"
74
75     Will enable syncing on green for sync-on-green monitors (these are
76     typically fixed frequency workstation monitors).
