You can install RedHat on your machine via serial console. So let start.
Get your machine to boot from the diskette in RedHat package or
you create
And run the installer.
After your machine reads the diskette for one minute or so,
it stop reading.
Now you are in the boot prompt.
Type next one line and press enter key.
This line is a little bit long, so
be careful.
Line is like this:
vmlinuz initrd=initrd.img text nokon lang=en console=ttyS0
Now you can see here the messages from the installer
via serial console.
And you can continue to install system via serial console.
This way of installation also works on VineLinux and TurboLinux.
