Proliant 5000r Red Hat 8.0 memory

[John Rowan_2]

I have three Proliant 5000r servers. All were running fine under v 7.x of Red Hat. I upgraded a test machine yesterday to version 8. It took close to 3 hours for the NFS mounted upgrade to complete (about twice as long as other 8.0 upgrades I've done). This machine was on v 7.3. Because of some BIOS related issue where all available memory is not reported to Red Hat the LILO configuration file (and the installation for that matter) had to have the parameter mem=exactmap mem=640k@0m mem=255m@1m to have the 7.3 machine see all the memory. The lilo.conf file has the proper work-around but 8.0 is not seeing it. Listing the /proc/meminfo shows only 12MB available. I examined the /var/log/dmesg file and it does not show the lines
user-defined physical RAM map:
user: 00000000000a0000 @ 0000000000000000 (usable)
user: 0000000017f00000 @ 0000000000100000 (usable)

any longer (above pasted from another 5000 dmesg file). Does anyone know how to tell Red Hat 8.0 about the 256MB RAM this Proliant 5000r has for it to use?

Don't have a solution, but my 1500 does the same under SuSe 8.1. Haven't tried an earlier build yet.
