I think that's true on sparc where OBP guarantees to enumerate the motherboard devices before any add-in cards, but there's no such guarantee on the ordering of enumeration on x86 systems. It's not uncommon to find a couple of add-in cards get e1000g0 and e1000g1, and the ones on the motherboard labeled "0" and "1" actually end up being e1000g2 and e1000g3. The easiest way to avoid this is to install and bring up Solaris for the first time before putting any of the add-in cards into the system. Alternatively, you have to edit /etc/path_to_inst afterwards to make the instance numbers match the labels on the back of the box. If you do force the instance numbering in either of these ways, you have to be aware that if you boot the system without this /etc/path_to_inst file (e.g. you boot from CD or you do a fresh install again), then the instance numbers will be different from what you got used to and again not match the labels on the box. -- Andrew
