This directory contains a bootable floppy disk image that should allow you
|
|
to boot linux on any 386 or 486 PC with a supported ethernet card.
|
|
|
|
The kernel is linux-pl10 + ALPHA-diffs + one line fix + minor ioperm mods
|
|
(which you really don't want to know about).
|
|
|
|
|
|
FILES
|
|
-----
|
|
README -- this file.
|
|
linux-pl10a.gz -- the bootable root disk image.
|
|
scsi-xt-boot.gz -- boot floppy with scsi, xt kitchen sink etc support.
|
|
usr.bin.tgz -- user networking binaries *unpack in /usr*
|
|
usr.etc.tgz -- networking daemons etc *unpack in /usr*
|
|
keymaps.tgz -- non UK keymaps (cp to /etc/keymap)
|
|
|
|
INSTALLATION:
|
|
------------
|
|
You can copy the image onto a floppy from most unix/linux machines with:
|
|
gunzip < linux-pl10a.gz | dd of=/dev/fd0 bs=18k
|
|
|
|
Under msdog you will need to gunzip (with gzip.exe -d) the image then copy
|
|
it to a floppy with rawrite.exe.
|
|
|
|
|
|
LIMITATIONS:
|
|
-----------
|
|
|
|
The image will only fit on a 3.5" drive, so you must have a 3.5" drive as A:
|
|
|
|
Booting is slow, the disk got pretty fragmented in setting up and I didn't
|
|
use the lilo fast read options which don't work on all machines.
|
|
|
|
The bootable root disk only has ide, nfs, minix, ext2, mouse and math emu.
|
|
|
|
If you want to have SCSI or XT disk support, you will need to use the scsi
|
|
boot image and then insert the bootable root disk at the prompt. (i.e. back
|
|
to the old boot and root disk system).
|
|
|
|
UPDATE: the scsi-xt image now has all standard filesystems (i.e. ext and
|
|
xiafs are in).
|
|
|
|
If you are on the Oxford campus the image will mount a /usr partition from
|
|
ftp.robots, else where you must provide your own /usr. Attempting to mount
|
|
from ftp.robots will force me to remove this service, the current linux nfs
|
|
code will produces far to high ethernet and nfs server load to not cause
|
|
major disruptions.
|
|
|
|
Although the ftp.robots /usr partition contains Xfree86, it is not possible
|
|
to run it over nfs as mmap is not supported over nfs (please feel free to
|
|
implement this and send the patches to linus - it isn't _that_ hard...).
|
|
|
|
|
|
WHAT YOU NEED TO KNOW:
|
|
----------------------
|
|
You need to know the following information before you can successfully use
|
|
this boot image - make sure you know the configuration answers before
|
|
attempting to boot!
|
|
|
|
1) Permission of your local netadmin.
|
|
2) Your PCs host name.
|
|
3) The IP address of your PC.
|
|
4) The IP address of the gateway/default router out of your network.
|
|
5) The netmask for your network
|
|
|
|
If you are outside Oxford you also need:
|
|
6) The IP address of your local named server.
|
|
7) a /usr partition that you can mount which contains the networking daemons
|
|
in /usr/etc and user binaries in /usr/bin
|
|
|
|
If you are not on a B or C class network the you will also need to know:
|
|
8) Your broadcast address
|
|
9) The net address for your network - what default packets for your local
|
|
ethernet are routed to.
|
|
|
|
|
|
BOOTING:
|
|
-------
|
|
Supported cards are
|
|
The Novell NE-2000
|
|
The 3c503 EtherLink II
|
|
WD80x3 Western Digital (SMC) WD80x3. *#!
|
|
|
|
If you don't have one of these you are on your own.
|
|
|
|
*#! WD80x3 cards must have the shared ram address at 0x4E000 for them to work!
|
|
Use wdsetup under linux or ezsetup under dos to set this up.
|
|
|
|
Alternatively if the auto configure doesn't work you can stop the boot at the
|
|
lilo prompt and give the ethernet card options there as
|
|
ether=IRQ,IOADDR,SHMEMSTART,SHMEMEND,IS8BIT,eth0
|
|
|
|
e.g.
|
|
LILO linux ether=10,0x300,0x4E000,0x52000,1,eth0
|
|
|
|
|
|
INSTALLING FROM THIS BOOT IMAGE:
|
|
--------------------------------
|
|
|
|
The aim of this image was to allow people to try linux before committing
|
|
themselves. It should be possible to also use it as an install base.
|
|
|
|
Use fdisk and mkfs prepare your hard disk in the normal way. Then mount the
|
|
new root partition on /mnt and you can use the /bin/copy_rootdisk script to
|
|
copy everything to your new root partition
|
|
|
|
e.g.
|
|
|
|
#mount -t ext2 /mnt
|
|
#/bin/copy_rootdisk
|
|
|
|
Then edit /etc/lilo/config (/etc/lilo/config.hda is an example hard disk
|
|
setup) and run:
|
|
|
|
/etc/lilo/lilo -r /mnt
|
|
|
|
to install linux on your hard disk.
|
|
|
|
If you don't have a UK keyboard, remove /etc/keymap (for US keyboards) or
|
|
replace /etc/keymap with the correct map from the keymap.tgz archive.
|
|
|
|
The rest is up to you.
|
|
|
|
|
|
BUGS:
|
|
----
|
|
|
|
The binaries in usr.bin.tgz and usr.etc.tgz, are recent but possibly not the
|
|
most bug free, if you know of a superior version of any of these please mail
|
|
me at the address below. rlogin does works between a PC and SUN which makes
|
|
a change
