RHEL 4 or 5 AS 64Bit OS

[Steve Clark]

I have not had a chance to test if this problem has been resolved with update 5.  We are using RHEL 4 Update 4 for our PXE boot image.   We normally do not build too many of the 2950 models with 16GB of memory, so it hasn't been a high priority.   I am also still waiting for several of our applications to become certified with update 5 before I can move that direction.

Thanks Steve,

Do you know if the memory issue was resolved with any of the updates to
RHEL4?  Which update of RHEL 4 were you using for the initial
installation?

Thanks
Vince
