    TITLE: SCO OpenServer 5 UNIX Lock Up Bravo MS

    SUMMARY

       SCO OpenServer 5, may appear to lock up during installation.

       This issue affects the following systems: 501920, 501921, 501922,
       501980, 501981, 501894, and 501895.

    ISSUE

       The keyboard locks up during SCO OpenServer 5 installation on
       Bravo MS systems.  The system does not accept any keyboard input.

    BACKGROUND

       The SCO OpenServer 5 keyboard driver does not respond to keyboard
       input causing the system to lock up.

    ACTION

       The keyboard driver needs to be updated.  To create an update
       diskette, perform the following steps:

        1. Connect to ftp.sco.com (preferably with a UNIX system)
        2. cd to the /SLS directory
        3. Obtain files OSS424A.Z and OSS424.LTR.Z
        4. Change directory to /AHS/5.0/sco/5.2
        5. Obtain files BTLD_135DSK.DD and EN_INST.TXT
        6. If these files were not copied directly to a UNIX system, copy
           them to a UNIX system now.
        7. On the UNIX system, uncompress -v *.Z
        8. Insert a blank, formatted floppy diskette into the UNIX floppy
           drive.
        9. dd if=oss424a of=/dev/rfd0 bs=36k
       10. Remove the diskette and label it "keyboard fix (kbp)"
       11. Insert another blank floppy diskette
       12  dd if=btld_135dsk.dd of=/dev/rfd0 bs=36k
       13. Remove the diskette and label it "ATAPI fix (wd)"
       14. Boot the Bravo MS system with the SCO OpenServer boot diskette
       15. At the "Boot:" prompt:
           defbootstr ahslink="kbp wd"
       16. When prompted, insert the kbp diskette
       17. When prompted, insert the wd diskette
       18. Enter "r" to replace the wd driver
       19. Follow the remaining steps to install OpenServer 5.

    NOTES

       If customers cannot find the files at the location stated above,
       on SCO's ftp site, customers should contact SCO at (800) 347-4381
       for the file locations.
