apt-get trying to install new packages in floppy disk

["Yi Wang" <wymail@gmail.com>]

Hi all,

I just did a minimum net-install to a server. Now when I tried to do
"apt-get install openssh-server", I saw the following error messages:

"After unpacking 569kB of additional disk sace will be used.
0% [Working ]hde: Invalid capacity for disk in drive
hde: 0kB, 0/0/0 CHS, 0 kBps, 0 sector size, 15536 rpm
hde: Invalid capacity for disk in drive
hde: 0kB, 0/0/0 CHS, 0 kBps, 0 sector size, 45116 rpm
Media change: please insert the disc labeled
'Debian GNU/Libux 4.0 r0 _Etch_ - Official i386 NETINST Binary-1 20070407-11:29'
in the drive '/cdrom/' and press enter"

But the hde is the floppy disk... Even if I tried to put the NETINST
installation disk in the DVDROM, nothing happened (of course..)

I have only two partitions on a SCSI RAID: /dev/sda1 mounted on / ,
and a swap partition.

Any hints?

Thank you for your help in advance!
