UW 2.1.3 adding memory

[Ayman Altounji]

I am adding 2 GB RAM on a Proliant 5500 running
under UW 2.1.3. There is now a total of 4 GB RAM

After booting, the 4 GB is detected by the BIOS. However, UW
detects only the old 2 GB (using /sbin/memsize).

I've added already the following line at the boot prompt (instead of making the change permanent in the /stand/boot file)

MEMRANGE=0-640K:256,1M-16M:512,16M-4096M:8704

No success although. The patch ptf4002b is installed as well. Didn't help either.

What else must be done? UW 2.1.3 supports up to 4 GB, so why won't it work?

You have to build a new kernel that has support for the 4 GB of memory. After the new kernel loads, all the memory will be available to the OS.

Robert,

could you provide any more details in the kernel rebuild? Which parameters must be modified? Do I only have to add the MEMRANGE parameter to the /stand/boot file. When I do this (without a kernel rebuild), the system doesn't come up after a reboot

Thanx,
Kurt
