SYMPTOMS
After installing Microsoft MS-DOS version 5.0, Sperry XT computers will not start from the hard disk, will not start from the Uninstall disk, and if started under a previous DOS version, a DIR command will display only random ASCII characters on the hard disk.



WORKAROUND
Upgrading the ROM BIOS to version 1.58 may correct this problem.



MORE INFORMATION
To obtain the latest XT ROM BIOS version (4.71), contact Sperry at (800) 448-1424, and choose option 4. You will be asked for the BIOS feature appropriate to the specific machine. To determine the BIOS feature of your machine, look on the back by the serial number for a TYPE CODE. If this code is   T3070-08, then ROM feature type (part no.) is F5083-02. T3070-00, then ROM feature type (part no.) is F5083-00. T3070-02, then ROM feature type (part no.) is F5083-01.
