The GoldStar Prime 2C MKIII is a Super I/O board from GoldStar using their own chipset.

The card's part number is P2C94002.

The TH99 entry has some mistakes, such as a jumper toggling between "primary IDE enabled" or "secondary IDE disabled". Since there is already a separate jumper to enable/disable the IDE interface, this is actually meant to switch the interface between primary and secondary when it is enabled. The same goes for the floppy interface.

This card is notable because the serial ports can be set to use IRQs 5 and 9, which will prevent them from conflicting with the default IRQs of 4 and 3, should the card be added as an additional controller.

The pinout for the serial headers is currently unknown. There are two types in common use. This page should be updated when the correct type is known.
