Hi,
we're running a Digital Unix 4.0d legacy system (with PK #3) on DEC
3000/300. However,
due to missing spare parts, we'll have to upgrade some machines to DEC
3000/600.
Furthermore, we're using a specifically tailored OS in order to provide
a dual boot
solution on a single hard disk and OS image downloads.
That's why I have to create an OS image which should run on the DEC 300
and 600 without
modifications.
Now I've tried to rebuild the kernel on a DEC 3000/600 - a plain
doconfig works, but so
far I couldn't create a kernel which supports both types of CPU:
1. just adding cpu "DEC3000_500" to the original DEC 300 config file
causes various 'multiply defined' error messages
2. merging a working config file for the DEC 3000/300 and the DEC
3000/600 provides the
same error messages.
3. After adding 'options MULTI_PLATFORM' doconfig complains about
undefined 'io_blockread'/
'io_blockwrite'
4. Rebuilding a generic kernel via 'GENERIC' config file also failed -
doconfig complains
about some ATM/otto stuff (although ATM is commented out in the
config file)
Unfortunately a google research provided no further hints, the DEC Guide
to System Administration
also did not reveal a solution (or I missed it :-( ).
The question is: How do I do this and which options do I have to include
in the configuration file?
Thanx in advance for any hints (or even solutions),
Volker Becker
