Subject: A question about zImage when booting from HD
Date: Mon, 06 Sep 1999 17:02:22 +0200 [thread overview]
Message-ID: <37D3D77E.D22665E2@fi.infn.it> (raw)
Hi,
after some time, I'm retrying to boot my board (a MVME2431) from the HD,
but still I have to use NFS. I partitioned the HD as:
Disk /dev/sda: 64 heads, 32 sectors, 8683
cylinders
Units = cylinders of 2048 * 512
bytes
Device Boot Start End Blocks Id
System
/dev/sda1 1 8620 8826864 83
Linux
/dev/sda2 8621 8680 61440 82 Linux
swap
/dev/sda3 * 8681 8683 3072 41 PPC PReP
Boot
then I create an image (make zImage) that is normally working when
booted by NFS (could be this the problem? there are some option to set
during the kernel compilation?) and copied it to /dev/sda3 using dd.
But when i tried to boot from the HD I obtain this:

Booting from: NCR53C825, Controller 10, Drive

IPL Size Exceeds Free-Available
Memory:
IPL Size =AC444000
(&-1404813312)
Free-Available Memory =01F74000
(&32980992)
I looked both in /dev/sda3 and in
/usr/src/linux/arch/ppc/prepboot/zImage and what I get is (the results
were the same):
[root@vmesez1 /root]# od -N 10000 -Ad -tx /dev/sda3
0000000 48000400 00000000 00000000 00000000

...
and I cannot figure from where I get this IPL Size =AC444000. If I
understand right what is written in the PPCBug manual it seems that the
code start at 1024 (byte 512), and the lenght is 0x095f6c (byte 516),
nothing related to AC444000; I'm missing something in the partion? Or
I'm using a wrong image?
Thanks
