- Installation can be tricky on a machine with 4 megabytes of RAM or less. Here
- are a few tricks that can be helpful if you run into problems. (Symptoms might
- include: system hangs while booting the bootdisk; root password required on the
- rootdisk; inability to run "fdisk" or "mkswap"; and many more, I'm sure...)
-
- If you have DOS and a 5 1/4" floppy drive, you can save 240K by using Loadlin
- in conjunction with a 5 1/4" rootdisk. Here's how:
-
- 1. Make the rootdisk using RAWRITE.EXE.
- 2. Unzip lodlin15.zip (look in /kernels) in a directory on your DOS partition.
- 3. Select an appropriate kernel from a subdirectory under /kernels. The
- /bootdsks.12/WHICH.ONE document might be helpful in selecting the proper
- one for your hardware. Copy it into the directory where you put loadlin.
- 4. Put the rootdisk into the floppy drive, and use this command to load it:
-
- loadlinx scsi root=b: ramdisk=1200
- ^^^^ ^^
- |||| This should be the drive you put the disk in.
- This is the name of the kernel you selected.
-
- Then, install as usual.
-
- ------
-
- There will be times when even that method doesn't save enough memory to allow
- installation. Here's another method that may possibly even allow installation
- to a machine with 2 megabytes:
-
- 1. If you have a second floppy drive, great -- you'll want to use that for the
- rootdisk. If not, you'll have to make due with the rootdisk in your boot
- drive. With the rootdisk in the boot drive you won't be able to install from
- floppy disks or make a bootdisk at the end of the installation process,
- since the disk will be "mounted" in the boot drive and cannot be removed (no
- matter what the screen tells you) until the machine is rebooted. Make a
- rootdisk using RAWRITE.EXE for the floppy drive you selected.
- 2. Unzip lodlin15.zip (look in /kernels) in a directory on your DOS partition.
- 3. Select an appropriate kernel from a subdirectory under /kernels. The
- /bootdsks.12/WHICH.ONE document might be helpful in selecting the proper
- one for your hardware. Copy it into the directory where you put loadlin.
- 4. Put the rootdisk (NOT write protected) into the floppy drive, and use this
- command to boot it:
-
- loadlinx scsi root=b: ramdisk=0
- ^^^^ ^^
- |||| This should be the drive you put the disk in.
- This is the name of the kernel you selected.
-
-
- Then, install Linux. If you're using the boot floppy drive for the rootdisk,
- you will not be able to install from floppy disks. DON'T take the rootdisk out
- of the floppy drive for any reason during the installation! Also, since scratch
- files may be written to the rootdisk, you'll want to start with a fresh copy if
- you need to start over for some reason.
-
- Once installed, you'll need to have a way to start your new system. If you were
- lucky enough to have a second floppy drive to use for your rootdisk, then you'll
- be able to make a bootdisk at the end of the installation process. This is
- highly recommended. If your boot drive is occupied by the rootdisk, then you've
- got two options: Loadlin (a method of booting from DOS) or LILO. And, if you're
- using the UMSDOS filesystem then Loadlin is your only choice.
-
- To boot the system with loadlin, you'll use a command similar to the one you
- used to start the rootdisk, but you'll replace a: or b: with the name of the
- device you're using for your root Linux partition, like this:
-
- loadlinx scsi root=/dev/hda2 ramdisk=0
-
- Once your machine is up and running, you'll probably want to switch to a
- different kernel, such as one of the ones on the A or Q series. The kernels in
- the /kernels directory are designed for installation and aren't as full-featured
- as some of the other ones. Or, you could compile a custom kernel especially for
- your machine from the source code in /usr/src/linux. This will provide optimal
- performance, since it won't contain any unnecessary drivers.
-
- Good luck, people!
