Out of 650 PCs that boot properly with the CD there are a couple Fujitsu
Lifebook T Series (not all of them, some Fujitsu's work) that experience
this issue with the NIC not being detected with a CD burned from Hot Patch
3. I can see the NIC with this command ifconfig eth0 up but
pump i eth0 h localhost.localdomain.com doesn't work. It say pump is not
found.

I tried the bootcd.iso from hot patch 4 and not only does it not find a
DHCP address but "ifconfig eth0 up" doesn't find eth0 on the laptop that
the hot patch 3 CD at least could see.

I got this from TID (3621123) and it helps define problem which is that
the CD doesn't find or activate the NIC but it doesn't suggest how to fix
the CD or perhaps ID whats wrong with this particular laptop because it
works on a couple others of this type so I think it has the right driver.

Network problems - NIC not being detected
Boot from disks in manual mode and then
Type ifconfig at the prompt, if it shows up the MAC address, NIC was
detected.
If step 1 fails, type ifconfig eth0 up, and then ifconfig, see if the
hardware details are shown.
If 2 does not work it means that the network card is not getting detected,
you might want to search for the drivers for that NIC, add that driver to
the second boot diskette using the linux boot utility, and then try
booting again.
Hint: To check if any given driver will work (only for desktops, not for
laptops), instead of adding the driver through second bootdisk, do the
following:

Boot in manual mode, copy the driver to a floppy, mount the floppy, copy
the driver from the floppy to the area /lib/modules/2.2.14/net, type
insmod /lib/modules/2.2.14/net/<drivername>, then type ifconfig eth0 up,
and then ifconfig to see if the driver worked.

Network problems DHCP not working:

Boot from disks in manual mode and then
Type ifconfig at the prompt, if it shows up the IP address, dhcp works
fine.
If step 1 fails, type ifconfig eth0 up, and then pump i eth0 h
localhost.localdomain.com, and then ifconfig, see if the IP address is
shown. (pump is the dhcp client)
If 2 does not work it means that the dhcp is not working. We could try the
following solutions:

try disabling plug and play, do a cold reboot, and then boot again, and
repeat above steps
copy another dhcp client namely dhcpcd, to a dos floppy, mount the floppy
to any directory (mount -t vfat /dev/fd0 /mnt/floppy), and then run the
command /mnt/floppy/dhcpcd, and then type ifconfig, see if it shows you
the ip address. To always use this client, changes are to be done either
to the zen partition (if problem is just with one machine), or to the
second bootdisks (if whole set of machines not working). To achieve this:

dhcpcd needs to be added to root.tgz file on the second floppy, or to the
bin directory on the zen partition.
The script network.s has to be changed and the line, "pump i eth0 h
localhost.localdomain.com" needs to be commented out, and replaced with
the line "dhcpcd".
