This manual describes the ASUS LS99 SCSI interface card, a proprietary PCI‑based expansion card that supports two independent SCSI channels and an optional 10/100 Ethernet controller. It explains the card’s physical dimensions, connector types, and supported SCSI modes (Fast, Ultra, Ultra2, Ultra160).
Installation procedures cover locating the ASUS‑specific expansion slot, securing the card, and connecting internal and external SCSI cables. Configuration sections show how to enable or disable the SCSI and network controllers, set SCSI IDs, and adjust terminal resistor settings. The document also includes cable‑length limits and performance tables for different SCSI standards. This manual is written in Chinese.
