RE: [Xen-ia64-devel] [FYI] Recipe of build and boot of Xen/IA64

["Magenheimer, Dan (HP Labs Fort Collins)" <dan.magenheimer@xxxxxx>]

Thanks to Akio's recipe and all the work on the new
version of elilo by Fred and Alex, I have successfully
booted dom0 and domU under RHEL4 so I am finally shifting
all my development and testing from RHEL3 to RHEL4.2
and from gcc3.2 to gcc3.4.4.

I was out of the office for a few days and returned
to a crashed system disk so I focused on getting
everything running on RHEL4.2 rather than reinstall
RHEL3.  As a result, I am behind on applying patches.
I hope to catch up in the next day or so.

Thanks,
Dan
