Jumpstart on X86 (PXE)
zii kell
afore on SPARC only, but expect that I will have to start to use x86.
I looked into the PXE configuration a little and would like to know if
jumpstart for x86 (Sun z20 z40) clients actually works, and whether it
would work with flash archives.
Would I be correct to assume that I could power on a Sun z20, and drop
into something that resembles an OBP environment and enter 'boot net -
install' somewhere?
Best regards, z.

No. x86 has no OBP or similar. But many (including the Sun servers)
support PXE booting, which the Solaris jumpstart can use.

Why does it not understand RARP?

You could use an existing one, but it's not always straightforward to
add the additional configuration, especially when it is not under your
control.

Because RARP/Bootparams is Sun specific and was never supported by
PCs.

Both are possible. The sun documentation isn't going to give
configuration instructions for other DHCP servers, but there are some
guides on the internet for it.

Nowadays, RARP is non-standard. Commodity x86 equipment commonly
supports PXE, using DHCP. DHCP can routed and handled by centralized
equipment, while RARP needs separate servers on each subnet.
RARP boot would require hardware/bios work that I doubt anyone wants to
do.

you don't need the macros for PXE booting, it only uses well known
DHCP options. for SPARC, you need vendor options which are different
for each hardware model. (the internal options are the same, but the
vendor option namespace has a model specific name.) once set up, you
don't need rarpd and can bootstrap on any subnet which has a dhcp
helper defined.

this documentation is only complete enough to install on a Solaris
server...
BTW, if anyone needs it, I have a Perl script to simplify configuring
a Windows DHCP server for Jumpstart, it simply emits a netsh script.
