[rescue] O2 rescue: advice for an SGI (relative) newbie

[Michael-John Turner]

Hi all,

I've just acquired my first SGI system, an O2. It has 128M RAM, 
a 150 Mhz R10K CPU and came with 2x4G drives (one internal, 
one external). Luckily it came with IRIX media - both 6.3 
and 6.5.4.  I'm busy downloading the 6.5.22 maintenance 
update (I don't have a support contract :P)

Today I purchased an 18G SCA drive to replace the internal
drive and I'm going to hunt around for more RAM (I'd guess
that 512M would be a comfortable target?) Anyone have any
RAM they're looking to sell?

A few questions:
(*) How best should I slice up the 18G drive? Should I split 
    it into different slices/partitions for different filesystems? 
	 I see the IRIX docs mention having a single slice. I prefer
	 having /usr, /var, etc as separate slices, or is that too
	 much hassle with IRIX?
(*) I'm planning to use NetBSD pkgsrc for management of additional
    software. Is that a good idea? Any alternatives?
(*) Is there any way to get USB working (eg with a PCI card)?
(*) Is it true that I can upgrade to an R12K CPU? I've seen some
    reference to CPU upgrades, but I'm not sure how far I can
	 take this baby?

Thanks in advance! I haven't used IRIX and SGI systems for about 
6 years, so forgive all the newbie questions :)
