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
