AIX 4.1.3 on 7009-C20 RS/6000

Hi there! Yeah, it never gets so far as to put any information up on the console. Only some LED codes that indicates it attempts boot, then goes back to the ROM menu. After some more research last night, looks like I'd need the 4.1.3 for Servers for D5 Processor Group, so this media probably isn't going to get me anywhere, even if I could try a NIM boot. As for why 4.1.3, I have some old stuff that requires that version. I'm fully aware that 4.3.3 or even 5.1 would probably result in a more useful system overall, and I have media kits for both, but 4.1.3 only is what's in scope right now. Anyway, thanks much! ________________________________ From: Rico Pajarola <rp at servium.ch> Sent: Monday, January 8, 2018 1:08 AM To: Benjamin Huntsman; General Discussion: On-Topic and Off-Topic Posts Subject: Re: AIX 4.1.3 on 7009-C20 RS/6000 As far as I remember trying to install the client version of AIX on a server type machine will bomb early in the installation, but it will give you some confirmation that it did indeed boot from the CD. Maybe your CD is indeed bad. Any specific reason why you want to run 4.1.3 and not 4.1.5, 4.2.1 or 4.3.3? (is there any hardware that only works with 4.1.3?).

I got my old 7009-C20 pretty tricked out and hardware carefully selected to be compatible with AIX 4.1.3, the version I'm trying to get running on it. Unfortunately, I can't get the dang thing to boot my 4.1.3 or 4.1.4 CD's. It'll boot my 4.1.5 disc, however. The 4.1.3 and 4.1.4 CD's are labeled "AIX for clients" or something like that, and I seem to recall having trouble getting other RS/6000's to boot from this 4.1.3 CD, even though it's genuine original media, and reads just fine in a working system. Anyone know a way to check what systems an old AIX 4.1 disc supports, or have C20 or similar MCA machine running 4.1.3? My other thought was to try to NIM boot it using my ThinkPad 860 as a NIM server (running 4.1.5), but it unfortunately doesn't have enough capacity to hold a lpp_source and a SPOT, and even then it looks like the 4.1.3 disc may not have enough stuff on it to support the C20 anyway... Anyway, thanks in advance!
