This is a hardware failure long before you get to SCO.
From the error message talking about ROM shadow it appears that that you have a memory problem where it is attempting to load ROM code into a RAM segment.
Think I saw one of these a long time ago but didn't get interested in the hardware details.
You may want to look at the OS version again. Don't recall a 5.0.06 but SCO put letters at the end of the version on the boot floppy that created confusion. I suspect you have 5.0.0.
If it is a memory problem you may have issues getting parts. You might consider replacing the hardware. DELL stuff that will handle the OS is selling on the used market for under $25 if you can reuse the I/O gear and reload the operating system and applications.

ncdnode(5) File Formats Manual ncdnode(5)
NAME
ncdnode - maximum number of open CDFS files (system-wide)
VALUES
Failsafe
Default
Allowed values
The minimum value allowed is The maximum value allowed is memory limited.
Specify a positive integer value.
DESCRIPTION
defines the number of slots in the inode table for in the CD-ROM file systems (CDFS). This number limits the number of open nodes that can
be in memory for CDFS file systems at any given time. It is functionally similar to but applies only to CD-ROM file systems.
Who Is Expected to Change This Tunable?
This tunable may need to be modified on systems that run applications requiring access to CD-ROM file systems.
Restrictions on Changing
The kernel module, which provides the file system type specific support for CD-ROM file systems, is now a dynamically loadable kernel mod-
ule (DLKM). Any changes to the value of the tunable will take effect after the kernel module is unloaded and re-loaded (see kcmodule(1M)),
or after system reboot.
When Should the Value of This Tunable Be Raised?
The value may need to be raised when running applications which require large numbers of simultaneously open CDFS files.
What are the Side Effects of Raising the Value?
More system memory will be consumed for the CDFS nodes. A larger static inode table for CDFS will be created based on the value of upon
kernel module load or system reboot
When Should the Value of This Tunable Be Lowered?
The value can be lowered to limit the number of CDFS open files on the system and reduce memory consumption.
What are the Side Effects of Lowering the Value?
Less system memory will be consumed for the CDFS inodes upon kernel module load or system reboot.
What Other Tunable Values Should Be Changed at the Same Time?
None.
WARNINGS
All HP-UX kernel tunable parameters are release specific. This parameter may be removed or have its meaning changed in future releases of
HP-UX.
Installation of optional kernel software, from HP or other vendors, may cause changes to tunable parameter values. After installation,
some tunable parameters may no longer be at the default or recommended values. For information about the effects of installation on tun-
able values, consult the documentation for the kernel software being installed. For information about optional kernel software that was
factory installed on your system, see at
