                            INSTRUCTIONAL NOTES

            Note: To install XEBEC 1220 on your system, access the Drive
            Type Table that corresponds to your on-board BIOS and select
            your drive type. Set drive type jumpers W5/1-W5/4 as
            indicated and use the ROM address to access the BIOS Address
            Selection Table. W4/1-W4/7 jumpers should be set according to
            this table.

            Note: Drives with IBM or Xebec formats use DOS FDISK.COM to
            set up partitions and DOS FORMAT.COM to initialize
            directories & create boot tracks. To format drives with no
            low level format, run IBMs adv. Diag. Program option 17 or a
            Menu Program accessible through DOS DEBUG.COM (available for
            BIOS types 104959 and 102168). If DEBUG.COM is selected, use
            drive type characteristics to select a ROM address from the
            tables. Set W4 to reflect this address and at the hyphen
            prompt, enter "-g= ROM address"
