Unable to read "/dev/hda"

["linux-anc@libero.it" <linux-anc@libero.it>]

Hello,

I'm trying to install a debian Woody on a Compaq Evo N1015v laptop, 
but a big problem stops my work: 
- if I start with the parameters: bf24 noapic nomce, 
when I try to partition my HD, I've got the
following error:

fdisk: unable to read "/dev/hda"

- if I start with the parameters: bf24 noapic nomce ide=nodma

the istallation hangs when I had to choice the installation language
(or the keybord does not respond)

The problems occours both I disable the DMA from the Bios or not, but if I
remove the nomce parameter, the installation fails with a kernel panic but I can
read the installation correctly detect the DMA and the partition table.

I'm using the CD installation of Woody 3.0r0.

Does anybody can help me?

Thanx a lot
