openSUSE 12.1 DVD boot fails but 11.4 succeeds

English Install/Boot/Login

Good day

I’m attempting to install openSUSE 12.1 on my desktop PC but my system gets stuck on the DVD boot process.

Firstly when I wrote the openSUSE 12.1 x86_64 DVD I verified it using the checkmedia application.
After that I test booted it on my laptop without any problems.

The problem I have is that as soon as I try to boot it it stops right after this:

ISOLINUX 4.04 0x4eac4005 ETCD Copyright (C) 1994-2011 H. Peter Anvin et al

However my older openSUSE 11.4 x86_64 DVD boots just fine and starts the boot loader right after:

ISOLINUX 3.86 0x4d643f2e ETCD Copyright (C) 1994-2010 H. Peter Anvin et al

I suspect that some change to ISOLINUX between 3.86 and 4.04 or the boot loader right after it is causing this due to an incompatibility with my system (BIOS interrupt call?).

Any idea what this might be or of a workaround?

It looks looks like this could be difficult. Do you have any BIOS settings you can tune?

Did you burn the DVD to a high quality +R or -R (not an RW) at the slowest speed your burner allows?

The motherboard is an ASUS one and there are quite a few settings that I can tune, unfortunately i don’t know what to look for.

I burnt both the 11.4 and the 12.1 discs on HP DVD+R 16x media, unfortunately I can’t remember at what speed they were burnt.
Originally thinking that it might be the +R media I also burned it to a BenQ DVD-R 8x disc with the same results.

When you say you verified using check media - I don’t know what that means.

Did you check md5sum of downloaded iso file against that posted on download website?

Burn at slowest speed burner allows -its important in cases like this.

is it safe to assume that this is a different machine than yours with
