Pci Ide Support - Viglen VIG520S Manual

PCI IDE Support

If Auto is selected as a primary or secondary IDE in Setup, the BIOS automatically
sets up the two local-bus IDE connectors with independent I/O channel support. The
IDE interface supports hard drives up to PIO Mode 4 and recognises any ATAPI
devices, including CD-ROM drives, tape drives and Ultra DMA drives. Add-in ISA
IDE controllers are not supported. The BIOS determines the capabilities of each
drive and configures them so as to optimise capacity and performance. To take
advantage of the high-capacity storage devices, hard drives are automatically
configured for logical block addressing (LBA) and to PIO Mode 3 or 4, depending on
the capability of the drive.

and Play ISA cards.
