Description
ASPI8XX.SYS is an ASPI manager which provides an interface to popular ASPI
applications. It is required when you want to use SYMDISK.SYS or SYMCD.SYS,
or whenever you want to run an ASPI application.
ASPI8XX.SYS replaces an SDMS BIOS (if present), and fully supports all devices
supported by the BIOS. If an SDMS BIOS is not present, only an ASPI interface is
provided.
