Booting from CD fails on Netra i

About SplackI\'ve got an old Netra i (UltraSPARC 143, SCSI, SBUS) and would like to install splack. I spent many hours this week trying to get it to boot from CD ROM with no luck.

I downloaded splack-08jul2k5.iso and burnt it to CD-R on my Slackware 10.2 x86 machine (Cdrecord-Clone 2.01 (i686-pc-linux-gnu) Copyright (C) 1995-2004 J?rg Schilling).

At the PROM I do boot cdrom. The error I get is \"The file just loaded doesn\'t appear to be executable.\" I looked at the FAQs (which are all many years out of date) and thought that mybe I needed an o.out kernel. So I tried making one, with a kernel from the CD image, gunzip\'s it and used elftoaout. I made a new ISO image with the script supplied.

However, it occurred to me that the kernel is probably not the problem, since SILO does not appear to be running.

I tried a new silo.conf file, and have burnt many CDs.

I also downloaded the NetBSD 3.0 sparc64 install iso image and burnt that, which works perfectly. Of course, NetBSD does not run SILO.

I ran .version in the prom. Here\'s the output:

Release 3.1 Version 1 created 1996/03/08 14:20
OBP 3.1.1 1996/03/08 14:20
POST 3.10.2 1996/03/14 05:10

I reckon my PROM should be able to cope with ELF binaries, if the ancient FAQs are to believed.

Does anyone have any clues as to what might be going wrong?

Thanks very much.

Oops! It says "Version 1" That means I need a.out, doesn't it? Do I need to convert SILO to a.out? How do you do that?

This should work OK, I have one of these machines.
The E150 / Netra i is an Ultra 1 mounted in a server cabinet with 10 disk slots.

Does the CD boot in another Sun machine, if not your download may have been corrupt.

The CD drives in these machines were rather slow and have problems reading CDRs. They cannot read CDRW media.
Always burn your CDR at low speed, 4x or less, to give these old drives a better chance of reading them.

SILO needs a block of contiguous memory starting at the Zero base address. Make sure that you have your largest pair of DIMMs mounted in U0701 and U0601 (diagram below).
DIMMs must be fitted in identical pairs.
The Sun supported DIMMs are :-

501-2479 16Mb Too small for SILO - Do not fit in U0701/U0601
501-2622 32Mb
501-2480 64Mb
501-5691 64Mb
501-3136 128Mb
All of the DIMMs are barcoded, look at the first 7 numbers printed below the barcode. For example 128Mb will be marked 5013136xxxxxxxxxxxxx.
