Unix General question

Posted on 1997-09-11
Last Modified: 2013-12-06
I created a new HP-UX kernel (v9.04) using the values suggested in the
Informix release notes (OnLine 7.12.UC1). Our machine is an E55
HP-server with 128 MB RAM. The system refuses to boot from this kernel.
Any help will be appreciated.

Your best bet here is to contact Informix and tell them that when you try to config your kernel to support their software, your system no longer boots!  They should be able to get you an answer quicker than the random chance that somebody here might have run across the same situation and solved it already.

Sound thinking. Only Informix support isn't what it used to be...
