Description
SYMDISK.SYS is needed when connecting drives with non-512-byte sectors, and
when connecting removable drives if the user wants to change the media. It is also
required to obtain drive letters for devices (adapters) that are not supported by a
BIOS. SYMDISK.SYS communicates through ASPI8XX.SYS. To use the
SYMDISK.SYS driver you must load ASPI8XX.SYS also.
