I've got a single proc. (166MHz and 128MB) and after the POST it says: Welcome to AIX; and list's all the proc. and memory info, then says: Closeing stdin and stdout... and just hangs there. It does scroll some codes across the LED for awhile but then goes blank only to do nothing. I've got the install disk for 4.2.1 and have tried to install it but get the same error when doing so. It has 2 4.5 Gig drives in it if that helps...
