Promise Technology Ultra33 9709-00 Rev B PCI IDE Controller Card ATA-33
The Promise Ultra33 is a PCI IDE controller card that adds two additional ATA-33 (Ultra DMA Mode 2) IDE channels to a desktop PC. It was designed to offload IDE traffic from the motherboard's built-in controller and to support the then-new Ultra DMA/33 standard, delivering burst transfer rates up to 33 MB/s — a significant step up from PIO Mode 4 drives of the era. This example is assembly number 9709-00, Revision B.

Applications
The Promise Ultra33 was a popular upgrade card in the late 1990s, when Ultra DMA/33 drives became common but many motherboards shipped with older PIO-only or DMA/16 controllers. It was widely used to add high-speed IDE support to Pentium and early Pentium II systems, and to connect additional hard drives or optical drives beyond the two channels the motherboard provided. Today these cards see use in vintage PC restoration and retro computing projects, where builders want to run period-correct hardware with properly supported ATA-33 drives. The card works with Windows 95/98/Me, Windows NT 4.0, and Windows 2000 using Promise's proprietary drivers.
This Promise Technology Ultra33 9709-00 PCI IDE controller card has been tested and is in good working condition. The card is clean with normal light handling wear consistent with prior use. Both IDE connectors and the PCI edge connector appear intact with no visible damage. Please view our photo set and contact us if you have any questions.
