I have one keyboard that works in DOS but on at least one computer
it works in DOS but in BL2 nothing happens when you press any key.
So I was going to try it with another linux, in this case
DamnSmallLinux on bootable CD-ROM. Even with CMOS set to boot from
CD-ROM, A, C it goes into DOS on the hard drive instead of booting.
I can look at files on the CD. Maybe the list member who gave us
this CD-ROM did not make it bootable as promised.

Or maybe your BIOS doesn't think it's a CDROM drive? You may need to
adjust settings to autodetect or hardcode in the fact that it's a CD
drive.

It gets detected during boot and I can read files from a CD-ROM with DOS.
I will try the same CD-ROM in some other computer since this one has two other problems - wont' boot FreeDOS and wont' work with one keyboard.


In the Knoppix directory of it is a boot.img file. How would I use
BL2 or BL3 to write this to a floppy disk and then what to I do
with it, assuming it is possible to boot from this boot disk to DSL
afterwards? The batch file to make floppy boot disk uses rawrite
so I could get that for DOS but I would like to learn to do this in
linux. Do I use dd somehow?

Assuming a low-level formatted floppy is in a drive at /dev/fd0, and
it's formatted to the proper size (e.g. 1440K) you just do dd if=file
of=/dev/fd0. If it's not formatted right you need to use fdformat. All
the rest should be handled automatically if the CD is in a standard
drive.
I will try this - presumably I boot from the floppy disk (boot sequence A, C, CD-ROM) with the CD-ROM in the drive too.


I could not find any mention of my keyboard problem - other people
only had problems after running certain software, or in X. There
was mention of 'faulty hardware' and someone lost their USB
keyboard and mouse at the same time. I cannot 'check if mouse
works' because I don't have gpm mouse. I suppose I could put
something in rc.S to load links -g to test the svga mouse. (Using
a different keyboard to type the change).
Other suggestions were to type stty echo or reset - don't know if
this would accomplish anything if the keyboard is not sending
characters.

All three green keyboard lights go on when I boot linux.

I don't need this keyboard, just curious what is happening. Also,
this computer is our only one so far that won't boot with FreeDOS.
Might it have a problem of some sort in the BIOS?

The BL2 FAQ appears have a similar problem listed--apparently you
need some extra kernel parameter(s)?
Thanks, will check this.

I am used to linux not working quite right on all hardware: so far
three computers won't work with loadlin except from MS DOS 7.1
(kernel on MS-DOS 7.1 formatted HD or FD), two won't play stereo
wav files, two won't boot loop linux, and now this odd keyboard
problem, and one 386 laptop won't boot linux of any sort. I am
certain nobody tested this keyboard with linux when it was made (in
the mid 80s).

Does anyone else on the list besides vijay (modem) have hardware
that won't work with BL but will work with other linuxes? I have
found the opposite to be true.

None of my new hardware works (duh) but my ISA PnP modem doesn't like
2.2.x kernels so I compiled a new one.

Could this be Vijay's problem?
