add support for asynchronous disk I/O to the kernel
add or remove support for American Power Corporation
uninterruptible power supplies (UPSs).
The installation process adds the script
S99apcssd to the /etc/rc2.d directory.
This script starts the UPS serial
port monitoring daemon ssd (/usr/lib/apc/ssd)
when the system goes to multiuser mode.
When prompted, enter
the full pathname of the modem control device (for example,
/dev/tty1A or /dev/tty2A)
and the expected battery life (default is 300 seconds).
This information is written to the file /usr/lib/apc/ssd.ini
which ssd reads when it starts.
For the correct cable, contact your UPS manufacturer.
The cable required to use this UPS
monitoring product on an American Power Conversion UPS
is APC part number 940-0023A. For further information on
APC UPSs, call 800-890-4APC (US and Canada) or

create bootable, root and filesystem floppy disks
Several floppies can be created during a single mkdev fd session,
but mkdev does not display a prompt to remove the first floppy
and insert the next one.

Use of this command is not recommended; use the SCOAdmin

mkdev fs creates the mountpoint and lost+found

on virtual disks.
If a SCSI hard disk is being added, the appropriate
host adapter and peripheral driver are also linked into the kernel.
USB devices can also be configured with mkdev
hd and are configured like SCSI hard disks; see also
The -u option prints information about adding a disk; the
-h option prints information about adding disks of a
different type to the root hard disk.
The -n (non-interactive) option is used when installing
the root hard disk.
Without options or arguments, mkdev hd runs
The command line syntax for disks with IDE(ST506),
ESDI, IDA, and OMTI interfaces is:
mkdev hd drivenum ctrlnum
the number of the disk on the disk controller; 0 for the first, 1
for the second.
the number of the disk controller being installed.
If the controller is of the
same type as the root controller (ctrlnum 0), it is
numbered 1 for the second, 2 for the third, and so on. If it
is a different type to the root controller, the numbering starts
at 0 for the first new controller of this type, and the number must be
prefixed with one of the following codes:
One ESDI controller with two disks is supported on
MC architecture machines.
Six Compaq IDA/Intelligent Array Expansion controllers
are supported on EISA bus machines.
One OMTI controller with two disks is supported
on AT architecture machines.
Two IDE controllers with two disks each are supported
on AT architecture machines. MC architecture
machines may have one IDE controller with two
For example, the command mkdev hd 1 IDE-0 configures
a second disk on the first IDE controller.
The syntax for SCSI disk installation has the form:
mkdev hd ID number lun ha [ bus ]
Here the arguments have the following meanings:
the target ID of the disk controller on the SCSI bus
(0-6 for SCSI 1, 0-15 for 16-bit wide SCSI 2;
note that the host adapter is usually assigned ID 7).
the number of the SCSI host adapter using the
hatype driver (for example, 0 and 1 for the first and second
adapters using the eiad driver; 0 for the first additional
adapter using a different driver). If the root disk is not
SCSI, the number must be prefixed by SCSI-;
for example, SCSI-1.
the logical unit number (LUN) of the disk on the
controller (always 0 for disks with embedded controllers)
the type of host adapter (supported types are listed
the number of the host adapter bus to which the disk is
connected; 0 for the primary bus, 1 for the secondary, and so on.
The default value is 0.
For example, the following command configures the second
disk on the first Adaptec 154x SCSI adapter where the
root disk is non-SCSI:
mkdev hd 1 SCSI-0 0 ad
mkdev hd must be invoked twice to install a SCSI disk.
The first time, the kernel is reconfigured to support the new disk.
The system must then be rebooted and mkdev hd run a second time
to initialize the disk. Use the same arguments to mkdev hd

configures the behavior of the scoansi
database entries and the in-kernel scoansi terminal emulator.
As of Release 5.0.6, console driver improvements have been made
that may cause problems with applications expecting the old
scoansi behavior. Basic terminal compatibility is provided in
the form of scoansi-old and scoansi-new
terminal database entries. SCO OpenServer systems prior to Release 5.0.6
and other UNIX systems performing remote logins should use
the scoansi-old terminal type (unless the system has
been reconfigured to use the old entries as described here).
You can use mkdev scoansi to change either the
database entries (affecting logins) or the in-kernel scoansi
emulator (affecting applications that use the scoansi control
sequences). The options are:
Changing the in-kernel emulator emulator causes the kernel to
be relinked and the system must be rebooted. See
for more information.
Use new (5.0.6 and later) terminal database entries
Use old (pre 5.0.6) terminal database entries
Use new (5.0.6 and later) in-kernel scoansi emulator
Use old (pre 5.0.6) in-kernel scoansi emulator
