When we're done, we'll have a floppy disk image.
This image can be written to a floppy that a PC can
boot from.
It can also be used as the El Torito boot file for a bootable
CDROM.
These images (floppy or CDROM) can also be run in
any number of PC emulators.
I've done a lot of my testing running them in qemu.
Set Inferno Configuration
Set the appropriate values in mkconfig in the Inferno
root directory.
Pay particular attention to the variables ROOT, SYSHOST,
and OBJTYPE.
Building the Tool Chain
If you're working in Windows, you already have the
toolchain in place in C:\Inferno\Nt\386\bin.
For other host OSs (Linux, FreeBSD, Plan9), an
"mk install" issued at a host OS prompt in the
Inferno root directory.
Be sure your PATH environmet variable includes
your Inferno binaries directory.
Configure the Native Kernel and Install Boostrapping Code
Don't worry, we're not installing the Inferno bootstrapping
code to your host machine.
We're just building it and putting it in a standard place so
we can use it later.
- In os/boot/pc in the Inferno tree, issue the command
"mk pbs.install 9load.install" at a host OS prompt.
- Edit os/pc/pc to set up the kernel configuration.
A simple/minimal set of changes to get something that
you can see working is:
- Change wminit to shell in the init section.
- Set the consoleprint variable in the code section to 1.
- Add the files /dis/lib/arg.dis and /dis/lib/filepat.dis
to the root section.
- Create a file in os/pc called plan9.ini.
If you're going to boot directly from the floppy, it should
include the line: "bootfile=fd0!ipc.gz".
If you're going to build a bootable CD, the line should
be "bootfile=sdD0!cdboot!ipc.gz".
This assumes your CD is the master drive on the
second IDE controller, which is probably the most
common configuration.
Build the Floppy Image
- Issue the "mk" command in os/pc at a host OS prompt.
- Issue the "gzip ipc" command in os/pc at an Inferno
shell prompt.
- Issue the following command in os/pc at an Inferno
shell prompt:
disk/format -b /Inferno/386/pbs -df disk /Inferno/386/9load plan9.ini ipc.gz
The result will be a file called "disk" that can be written raw
to a floppy or used to create a bootable CDROM.
