Installing Linux on ZIP disk using ppa ZIP Drive Mini-Howto: Setting up the ZIP disk
3. Setting up the ZIP disk(Common for both Red Hat and Slackware distributions.)
Before starting, make sure that you have access to the ZIP drive;
either by having ppa in the kernel or by having the ppa module
loaded. One easy way to find this out is by checking dmesg:==> dmesgYou may have to pipe this to more as dmesg tends to be rather long.
Here's a snip from mine:
scsi0 : PPA driver version 0.26 using 4-bit mode on port 0x3bc.
scsi : 1 host.
Vendor: IOMEGA Model: ZIP 100 Rev: D.08
Type: Direct-Access ANSI SCSI revision: 02
Detected scsi removable disk sda at scsi0, channel 0, id 6, lun 0
SCSI device sda: hdwr sector= 512 bytes. Sectors= 196608 [96 MB] [0.1 GB]
sda: Write Protect is off
sda: sda1 sda2If you only see something like:
scsi : 0 hosts.
scsi : detected total.then you have SCSI support but the ZIP wasn't found.3.1 Partitioning ZIP diskTo partition the ZIP disk, run fdisk:==> fdisk /dev/sda/Here is a snap of the partition table I have setup:
Disk /dev/sda: 64 heads, 32 sectors, 96 cylinders
Units = cylinders of 2048 * 512 bytes
Device Boot Begin Start End Blocks Id System
/dev/sda1 1 1 81 82928 83 Linux native
/dev/sda2 82 82 96 15360 82 Linux swapI decided to use a swap partition since I wanted to be able to use
this with any machine.3.2 Formatting and mounting the ZIP diskAfter running fdisk, format the new partition:==> mke2fs -c /dev/sda1Then, create the swap partition: (15360 blocks as taken from fdisk)==> mkswap -c /dev/sda2 15360Last, you'll need to mount the ZIP disk:==> mount /dev/sda1 /iomega -t ext23.3 Creating the boot diskSince the ppa version of the ZIP drive isn't a true SCSI device, it
isn't a bootable device and, therefore, requires a boot disk which
has ppa included in the kernel and not as a module.Configuring and making the kernelFirst, you'll need to configure and make a kernel that has ppa
support enabled and not as a loadable module. In order to get to
the ppa option, select SCSI support:SCSI support (CONFIG_SCSI) Y/m/n/?Plus, SCSI disk support:SCSI disk support (CONFIG_BLK_DEV_SD) Y/m/n/?And finally, under the SCSI low-level drivers, is the ppa support:IOMEGA Parallel Port ZIP drive SCSI support (CONFIG_SCSI_PPA) Y/m/n/?Again, be sure not to include ppa as a module, but rather in the
kernel. Thus far, without the use of the parport kernel patch
(see 1.4), the ppa driver will not allow the passive port of the ZIP
drive to be used for a printer, so you may want to say no to parallel
printer support:Parallel printer support (CONFIG_PRINTER) N/y/m/?
NOTE: For more information concerning the ppa driver, please
refer to the ZIP-Drive mini-HOWTO.Once the kernel is configured, make the kernel:==> make dep; make clean; make zImageThe new kernel should be found in arch/i386/boot/zImage.Getting the kernel to a floppyAfter having to have 4 separate floppies due to different kernels
and needing different parameters, (plus the great email I got
telling me how to do this) I have included a section on LILO as one
of the means of creating a bootable floppy.LILO installationFor those who have to, or for that matter just want to, have several
kernels on one floppy (now adays, mine are too large) or just want
to be able to pass arguments (such as single user mode) I received
email on how to install LILO on a floppy.Creating the ext2 filesystemTo create an ext2 filesystem on a floppy, just do the same command
for the ZIP disk:==> mke2fs -t /dev/fd0Copying the essential filesNext, make sure there's a directory for a mount point, and mount the
floppy (I used /mnt/floppy):==> mount /dev/fd0 /mnt/floppy -t ext2is to boot properly, you'll need the same files that LILO uses on your
current Linux installation.
NOTE: The file locations here are from my machine
and may not be the same for everyone.==> cp /boot/boot.b /mnt/floppy==> cp /boot/map /mnt/floppy==> cp /usr/src/linux/arch/i386/boot/zImage /mnt/floppy/vmlinuzDESKNow to create the config file for LILO, now I miss the liloconfig
program... (Thanks to Javier Rodriguez for this info) First, create
the LILO config file, /mnt/floppy/lilo.conf, for the kernel(s) for
the ZIP disk. Here's what I used so that I could have different
kernels to test with:
boot=/dev/fd0
map=/mnt/floppy/map
install=/mnt/floppy/boot.b
prompt
compact
timeout=50
image=/mnt/floppy/vmlinuzLAP
label=Laptop
root=/dev/sda1
read-only
image=/mnt/floppy/vmlinuzDESK
label=Desktop
root=/dev/sda1
read-only
image=/mnt/floppy/vmlinuzDESK
label=rescue
root=/dev/hdc1
read-onlyI have two kernels, one for my 486 laptop which required the math-co
emulation in the kernel and the other for my desktop. The rescue
allows me to make an emergency boot to the hard drive.Last but not least, with the floppy still mounted, run LILO to
install it on the floppy with the command:==> lilo -C /mnt/floppy/lilo.confOnce LILO has been installed on the floppy, skip the next two steps,
unless you enjoy doing this over again :)Kernel only installation
NOTE: This does not pertain for the LILO install.Copy the newly made kernel to a floppy disk:==> cp arch/i386/boot/zImage /dev/fd0or==> cat arch/i386/boot/zImage >/dev/fd0Yes, there are many ways to copy the kernel to a floppy, but the
last way, my favorite, is a little more encrypted. Try not to
forget the >unless you like viewing binary files :)Setting the root and swap on the floppy
NOTE: This does not pertain for the LILO install.Once the kernel is on the floppy, you need to set the root device to
the ZIP disk:
==> rdev /dev/fd0 /dev/sda1
I'm not sure if the next option is needed, but I did it none the
less. To set the swap:==> rdev -s /dev/fd0 /dev/sda2
