Resolving Keyboard Locking Problems When Copying Files from
CD-ROM
Check the hardware configuration on each network board in the server to
make sure that the configuration is correct.
If you recorded network board configurations and they do not agree with
the actual hardware configurations, reload the LAN driver with the
correct parameters or change the hardware settings to match the LAN
driver parameters.
Check all network board settings for possible interrupt and I/O port
conflicts. The server can boot up initially even if the interrupt on a
network board is set incorrectly.
The most common conflict occurs when a network board is set to
interrupt 4 and a printer is connected to the server's serial port, which also
uses interrupt 4.
Run a virus scan on the DOS partition.
To diagnose keyboard locking problems when copying files from CD-ROM,
identify whether the following conditions exist.
If you have a CD-ROM device that shares a SCSI bus with a disk subsystem
containing volumes that network operating system installation files are copied
to (typically volume SYS:), your keyboard might lock while loading drivers
or copying files to the volume. The following figure shows possible
configuration conflicts.
