## 1. Supported chipsets

The driver is used in the 8-bit / 256-color SVGA server and the mono server. The following chipsets for Oak Tech. Inc. are supported:

OTI037C

  8-bit SVGA chipset, with up to 256Kbytes of DRAM, only preliminary support is included in the driver as I don't have a 037c to test it.

OTI067

  ISA SVGA chipset, up to 512Kbytes of DRAM (usually 70/80 ns).

OTI077

  Enhanced version of the 067, with support for 1Mbyte and up to 65 Mhz dot-clock, this chipset supports up to 1024x768x256 colors in Non-Interlaced mode, and up to 1280x1024x16 colors Interlaced.

OTI087

  One of the first VLB chipsets available, it has a 16-bit external data path, and a 32-bit internal memory-controller data path, it also has register-based color expansion, hardware cursor, a primitive BitBlt engine, a 64 bit graphic latch and some other new (on its time) features. Maximum BIOS resolutions are 1024x768x256 Non-Interlaced and 1280x1024x256 interlaced. Maximum Dot-Clock is 80Mhz, but is usually coupled with the OTI068 clock generator whose highest frequency is 78Mhz. Supports up to 2MBytes of 70/70R ns DRAM.

OTI107 and OTI111

  These are new, PCI chipsets by Oak Tech. Inc. Support is not included for them, as they are very rare, and I haven't had the chance to look at one of these boards.

All the chipsets up to the OTI087 are "Backwards compatible", in fact some early drivers for the OTI087 based chipsets were those made for the 077.

Accelerated support is included only for OTI087 chipsets, also Mono server is only included for 067/077 chipsets.
