Debian Etch AMD64 fsck e2fsck

Using my motherboard and net install cd I have to type:

rescue pci=nomsi

to get rescue mode started.

after that I can execute a shell in the installer environment; then type at the prompt

# e2fsck -v -y /dev/mapper/hostname-partition

where hostname is my computer's hostname and partition
is a partition name like home, var, usr or boot.
