The following problems are addressed in Technical Articles that appeared
on SCO's web site in the week ending 20010428.

PROBLEM:  There have been several problems reported when trying to use a Mylex
          RAID adapter with a tape unit attached.  Although SCO ARCserve/Open
          will find and work with the tape unit in this configuration, there
          are other known issues when attempting to use all of the features
          of SCO ARCserve/Open.

          Problems that have been confirmed:

Phone and Email Support at Monthly rates

          1. The emergency root/boot floppies cannot be created using the
          'mkarcboot' command.

          2. ARCserve/Open will not see a tape changer.  This problem has been
          confirmed by Cheyenne working with Mylex.  The MDAC driver does not
          support multiple LUNs with the various SCSI ids.

PROBLEM: During installation of the SCO XENIX Development System, I am
           asked to choose a default terminal description library for use
           with the curses(S) screen handling package. I can choose
           "terminfo", "termcap" or "no default package" by selecting neither.
           Which curses package should I choose?

PROBLEM:  Client sorts a file by one field, then tries to do
another sort of the result by a different field.  Doesn't work
at all because the first sort is not being retained in memory.

PROBLEM:  I want to be able to mount a secondary filesystem (such as /u)
          at boot, so I can have access to the content in single-user
          mode. I've tried using the "At System Startup" option in the
          File System Manager, but it doesn't mount the filesystem until
          I go into multiuser mode.

PROBLEM:  I am attempting to restore my root filesystem using tape
          backups and emergency boot and root floppy diskettes.

          I have successfully booted my system from the boot/root
          floppy diskettes and have mounted /dev/hd0root onto the
          /mnt mountpoint. I have changed my working directory
          to /mnt.

          When I type this command:

               # cpio -icvud -I/dev/{tapedevicenode}

          I see this error message:

               NOTICE: HTFS: No space on dev ram (31/7)
               cpio: cannot write /_BACKUP_CONTENTS_:...
               ...No Space left on device (error 28)

          Why am I getting this error message and how do I restore
          my root filesystem?

PROBLEM:  My system is running out of clists even when the NCLIST is set
          at very high values.  Increasing the NCLIST kernel tunable
          parameter only allows the system to run longer between crashes.
          In some cases, the kernel seems to lose clists even when idle.
          For example, it will crash at night with no cron jobs running.
          The kernel message is:

           putc - Out of clists (NCLIST = xxxx exceeded); yyyy failures so far

          mail delivery agent.

PROBLEM:  Some or all of my users, possibly including root, are unable to
          use passwd(ADM) to change their password.  If root is affected,
          then root is unable to change other users' passwords as well.
          The user is prompted for the old and new password, but after
          entering the password the second time, they get the message:

             Password cannot be changed; see Account Administrator.

          In some cases, only root is affected; in others, all or some
          users are affected.  You may find you can change passwords in
          Maintenance mode, but not as root in multiuser mode.
