Based on SIS 5591 Chipset. ATA-33 or DMA/33 support. AGP support.

The M Technology Mustang AGP-R581A provides the latest enhancements in system board technology. Based on the SIS 5591 PCI chipset, the board provides high PCI-to-memory bandwith for today's demanding applications. The R581A supports 1MB pipelined burst Level 2 cache. The R581A is the first Socket 7 Mustang mainboard that support AGP slot. Processor support ranges from the fastest Intel Pentium 233MHz down to the least expensive 75MHz units. The R581A also support Cyrix/IBM 6x86 150+ to 266+. For the AMD enthusiastic, the R581A is equipped with a 2.9V and 3.2V Voltage selector for AMD K6 - 166 to 266 MHz CPU. It also support the IDT C6 200MHz cpu.
