# 1 Supported chipsets

Contents of this section

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:

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 (in its time) features. Maximun BIOS resolutions are 1024x768x256 Non-Interlaced and 1280x1024x256 interlaced. Maximun Dot-Clock is 80Mhz, but usually is coupled with OTI068 clock generator whose highest frequency is 78Mhz. Supports up to 2MBytes of 70ns DRAM.

All the chipsets are "Backwards compatible", in fact some early drivers for the OTI087 based chipsets were for the 077!!!!

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