I tried hard to install a laptop through PLIP with a RedHat 6.2 but
the installer from RedHat is buggy and could not be used for
PLIP. I verified that it was already broken in RedHat 6.1, but
works in RedHat 5.2 as desired. Patches have been sent to RedHat
and will hopefully be applied to the upcoming RedHat 7.0.
So if you want to install a RedHat 6.x over PLIP you must
follow these instructions.
The problem is the "bootnet" disk. This disk should be used for
PLIP installation but has 2 serious errors:
- it does not contain the necessary driver "parport_pc"
- it does not allow you to specify important module
parameters to "parport_pc" (especially "iobase" and "irq").
Probably the easiest way to solve the above problem is to use a
fixed "bootnet" disk. You can get a fixed "bootnet" disk for RedHat
6.2 from
http://www-ti.informatik.uni-tuebingen.de/~bubeck/bootnet-plip-62.img Use the following command to copy the downloaded image to an empty disk:
dd if=bootnet-plip-62.img of=/dev/fd0 .
Then insert the disk and turn your computer on. When you come to
the point where you must choose your network device driver please
do:
- 1- Choose "Parallel Port Module for PC" and select "specify
module parameters".
- 2- Enter iobase and interrupt for your parallel
port. Typical values are iobase=0x378 or iobase=0x3bc. Interrupt most
often is "irq=7".
- 3- Validate that the kernel loads the module and finds the
parallel port. Use ALT+F4 to switch to kernel messages and look
for a line saying: "parport: ... irq: 7".
- 4- The installation will then try to access the network
which is still not available. So the installer asks again for the
installation method. Choose your method again.
- 5- Now choose the "plip" module without any
parameters. Again verify the loading of the module in the kernel
messages.
- 6- Network should be up and running, installation should
proceed. If not, then check the modules parameters to
"parport_pc".
If the above bootnet disk is not suitable for your needs, I will
present a small description of how to transform a standard bootnet
disk for using "plip". This description is quite short and is
addressed to the advanced user.
By following these instructions, you get a bootnet disk containing
all necessary modules and therefore allowing for a PLIP
installation. Please follow the instructions elsewhere in this how-to
on how to do the installation with the new disk.
