I want to try to install Ubuntu again on my slave drive, after the
disaster the last time I tried with Ubuntu 5.10 and somehow got Grub
installed on my master and all data on all partitions on the master hosed.
I have the alternate install CD of Ubuntu 7.04, and have created a 256 M
Linux Swap partition and two 6.5 M ext/3 Linux partitions with DFSEE.
Jan van Wilk has been helping me get up the nerve to try again, and told
me how I should tell it to install Grub to the Linux partition /dev/hdb2.
I hope I can get it done correctly this time.
Is anyone else running this combo? I admit to knowing nothing of Linux,
little of XP, and not being too great with OS/2, which is why I always
appreciate the help I get.
At first when however you have to use eCS or OS/2:
You MUST use eCS to do any partitoning you have to to do.
You can't use linux for that without the risk of destroying the
partiton table.
You can't use windows for that without the risk of destroying the
partiton table.
However when you have an alredy installed windows and/or linux on a
hard disk and you have to install eCS you MUST use dfsee to fixup CHS
and partiton table before you can do something else.
However when you has no knowledge how linux is using the hard disks
you needs to learn a minimum before you tries to start to install:
Linux does never use drive letters but symbolic names:
- a physical drive has different names /dev/xyzn
/dev is the symbolic name of the directory that contains devises
such as screens, disks, floppies, printers and so on. Here I will
tell
only about hard disks because anything other can live on modern
linux
as it is and is of no interest here:
xyzn is a 3 letter combination that builds a disk name. Wjhereas
x = a single letter defining the type of a disk:
h stands for an (E)IDE drive
s stands for a SCSI drive
y = d stands simply for disk
z = a single letter from a to z
for IDE: a = first drive on primary controller
b = second drive on primary controller
c = first drive on secondary controller
d = second drive on secondary controller
for SCSI: a = SCSI ID 0
b = 1
and so on
n = a partiton number:
0 = 1. primary partiton
1 = 2. primary partiton
2 = 3. primary partiton
3 = 4. primary partiton
4 = extended partition, the container for logical drives
This thing is well hidden under windows and OS2/eCS
even as it exists
5 = 1. logical drive in the extended partition
6 = 2. logival drive in the extended partition
and so on
examples:
hda0 (E)IDE, primary controller, master, 1. primary partiton
hdb0 (E)IDE, primary controller, slave, 1. primary partiton
hda5 (E)IDE, primary controller, master, 1. logical drive in
extended partiton
hda9 (E)IDE, primary controller, master, 5. logical drive in
extended partiton
hda10 (E)IDE, primary controller, master. 6. logical drive in
extended partiton
As sayed above you have to to the whole partitoning with eCS:
preferred:
- IBM BootManager
free space on to of the drive
size: exactly 1 cylinder (depends on the size of the whole
physical drive)
eCS/OS2 LVM/fdisk determines the size and occupies a
primary partiton for it
C: 2. primary partiton on master, primary controller
windows/DOS
DOS/W9x: max. 2GB
Windows >9x: any size you likes for NTFS/FAT32
LVM type: compatible, bootable
x: 3. primary partiton (/dev/hda2) /boot
recommended size: 100 MB
gioves enouth free space to hold multiple LINUX kernels
will hold linux bootmanager
to let the LINUX bootmanager decide which of the installed
kernels to boot from here
LVM type: compatible bootable
hidden extended partiton
will be crated and maintanced by LVM/OS2 fdisk under the hood
when the first logical drive gets created
D: logical drive, resevered for windows data, optionally
size depends on the partiton type you'll use for win
You MUST create a volume from that partiton only when it should
be visible under eCS
w: optionally: more logical drives for windows
o: at least one, recommended more partitons for eCS/OS2
you MUST create volumes for each to get them visible under eCS
The logical drive you reserve for install eCS must be
LVM type: compatible, bootable, format /FS:HPFS
eCS 2.0 and up: can be LVM, bootable, format /FS:JFS
size: OS/2, eCS 1.0/1.1: 500 MB, eCS 1.2(R) 1GB,
eCS 2.0 1,5GB or bigger
recommended multiple other partitons/volumes:
LVM type: LVM, not bootable, format /FS:JFS; HPFS allowed
- reserved for / - the only one you nneds beside /swap
size: 20 GB or more recommended, 8GB required
- /swap
size: minimum: 2 x size of real RAM, more is better
When there is already a functional windows installation you may modify
the layout above:
At first before you do anything else:
- let the C: on the primary partiton it is already
- fire up DFSee most current version
required for XP and Vista, windows befor that optionally:
- let it fixup CHS mapping
- let it fixup mbr
this destroys nothing but makes the disk ready to work with LVM or
on
OS/2 prior to 2.4.1 to use OS/2 fdisk.
DON'T use fdisk on eCS and OS/2 4.51 and above! LVM is required
on them
On linux you MUST use the expert install. You have to change the
partiton types you'll install linux on manually to the linux partiton
types you want. In special UBUNTU will destroy any partion during
standard install. So never use the default, go through the
expert/advanced mode and be carefully to set right partions to the
right type. Don't do anything else with the partitons except setting
the right type, check and recheck to not destroy anything else.
As a real sample: I had had to modify a customer mashine that was
coming in with
C: primary XP system
D: primary XP data
E: primary XP data
- lot of free space
Job to do: install eCS 1.2R on it, leave XP intact.
The steps needed:
- use DFSee to fixup mbr and CHS to be ready for eCS.
- use DFSee to move the XP data partitons away into new
created extended drives
- use DFSee remove the primary partitons D: and E:
- use DFSee to create IBM BM immediately after C:
- use DFSee to create extended drives immediately thereafter
to bring the windows data back on theyr place
- use eCS installer boot to
- make a volume from C:
- insert C: into IBM BM
- create the partitons for eCS
- create volumes from the now already existent partitons
- format the new created eCS partitons
F: HPFS eCS system
G: JFS eCS programs
H: JFS eCS data
continue with install
after install:
- integrate mashine in my network and internet
Boot up to XP to check it's functional - success in all tests
Boot up eCS installer
- install ecsmt and fix the system up
- install some software in eCS
done!
About 4 hours work done, full success - except: touch screen not
working under eCS because impossible to get a OS/2 driver for it.
