Re: Going from 2.2.12 to 2.2.17pre10

Hi!

I'm trying to go from 2.2.12 to 2.2.17pre10 on an MVME 2400.

A few problems:

The Motorola SROM bug-patch lacks one row in de4x5.c:

        lp->infoblock_csr6 = OMR_MII_100;
        lp->useMII = TRUE;
        lp->infoblock_media = ANS;

This one was easy. Now for the hard one. :)

I'm using a PMC-harddisk based on the CMD-646 chipset (Ramix 233).

I installed my system under 2.2.12 with Debian.

When I come to the partition check in 2.2.17pre10 it fails with
"hda: unknown partition table"

I added a printout in drivers/block/genhd.c in msdos_partition()

        }
        p = (struct partition *) (0x1be + data);

With this I get the following printout:
hda:Data: aa55 LABEL:55aa

So it seems like the byte order is wrong. Does anyone know why this
happens?

Please don't tell me my 2.2.12 partitioned disk is wrong. :)
