2.2.17 + ide patches + 61gb ibm disc = problem

[Daniel Sangenberg]

Hi!

I have a problem with 2.2.17 + the latest ide patches and 2 * 61 gb ibm ide 
discs, the discs are connected as slave on a two channels (onboard ide 
channels on a asus p2b (i440BX Chipset)), there is nohing else connected on 
the ide interface and the jumper settings are identical.

dmesg output:

Uniform Multi-Platform E-IDE driver Revision: 6.30
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
PIIX4: IDE controller on PCI bus 00 dev 21

hdb1 [events: 00000001](write) hdb1's sb offset: 60050816


The difference in size and cylinders could cause a problem if this changes 
in later versions, is this normal behaviour or did i do something wrong ?

If possible please CC me when replying

I don't understand why you have set them to be slaves when they are the only 
drives on the ports.  Shouldn't you be setting the jumpers on both drives 
into the Single Drive (default) settings?  I always thought the Master and 
Slave positions are to be used only when connecting two drives on one port.

hda and hdc should be the devices.

You have the classic BIOS issue it only works half way.
pass the geometries to fix one side of the other.

This is true, what are you running in this bizzare mode?

This is normal behaviour. See
