it is a PC/XT-only or PS/2 keyboard). If this is the case, replace
the keyboard with a PC/AT style keyboard.
Memory parity interrupt at ...
Problem: This could be a software error (reading a nonexistent memory
area) or a true hardware failure.
Solution(s): Attempt to repeat the error. If the error occurs during the
execution of your own proprietary software, verify that the
memory location specified in your software is valid.
Missing operating system
Problem: Although the system could read the hard disk and find the active
partition, the operating system files could not be found.
Solution(s): This is can be caused by using a drive type number or head/
cylinder combination in the EPC-8A’s IDE Adapter 0 Master
Menu that does not match the type number used to format the hard
disk. Run the BIOS setup program. Select the Autotype fixed disk
option, or if known, correct drive type or User Editable parameters
to match the type used to format the disk originally. Save the
changes and reboot the system.
This can also occur if the hard disk is partitioned and one partition
is set active, but the partition does not contain the operating system
files.

Replace and press any key when ready
Problem: This is caused by an attempt to boot from a disk or diskette that is
not recognized as a system disk; that is no system files exist on the
disk or diskette.
Solution(s): Most often it results when you reboot with a nonsystem diskette in
the floppy drive, because the BIOS always attempts to boot from
the floppy drive if a diskette is installed.
If you are trying to boot from the hard disk, make sure that you do
not have a diskette in the A: drive and press any key.
If you are trying to boot from floppy, insert a known good
bootable system diskette in the A: drive and press any key.
Not ready reading drive ...
Problem: This is usually caused by not fully inserting a diskette into the
floppy drive.
Solution(s): Eject the floppy diskette and reinsert making sure that the diskette
seats completely into the floppy drive.
Parity error in segment ...
Problem: This could be a software error (reading a nonexistent memory
area) or a true hardware failure.
Solution(s): Attempt to repeat the error. If the error occurs during the
