[SunRescue] Max capacity of harddisk supported by SS20

[MikeHebeldruaga at pmail.net]

Is there a FAQ on Openboot Prom revisions?  I have a SS5 with a ROM of 2.15
and I'm about to re-partition (after backup) my 4 gig SCA drive for more
space.  (Newbieness caused me to break / and /opt into two separate
partitions.)

Am I going to have a problem booting if I make it all one big drive of about
4gig?

Sincerely,

Mike Hebel

No, what he means is that the kernel does not suffer from the 2GB
boundary. It's the OpenBoot PROM (In PC terms: the BIOS). It can't see
the kernel file if it's beyond the 2GB limit. That means you're OK if
your root (/) partition is within the first 2GB of the disk.
