Please, Sindi, this information is very important and should be

I thought everyone knew you had to unmount things such as floppy disks and
USB memory sticks and zip disks before removing them, but I will add a
reminder anyway.

The hot (un)plugging creates the illusion that it is different here.
And while mounting floppy and CD is only one step, here there are two
steps. One working as a demon, on that does not work this way. This
is what confused me.

I don't understand what you are saying.

For BL3 you need to insert three modules to use the CD-ROM drive, then you mount the CD-ROM (/dev/hdc), read from it, and umount it before you remove it. For USB sticks you need to insmod some scsi and usb modules first, then mount /dev/sda4.

With my latest kernel you don't need the modules but you still need to mount either of these.

Do you want ide-cd.o instead of built-in support?

I will certainly write a small shell script similarly to my a:, :a,
c:, :c, d:, :d which I use to mount and unmount the other block
devices.

How did David do this in his little 1-floppy linux?

David did not include neither links neither mc. The only 'browser-
tool' is zgv.

Didn't he automatically mount the USB stick at boot?


I think zgv at the moment is the only program using libvga. I will
install the library and zgv in its original version and see if it
works with the 2.4.31 kernel.
Okay, if you need an image viewer.

This is an open question. For the purpose of the modified RAM version
zgv could be interesting, but mc and cdrtools are more important.
Photographs form a substantial part of the data I want to transmit.
And short file names on my DOS hard disk partitions do not allow a
good identification. So it may be useful to have a viewer at hand.
Tomorrow I need to find out how much space the files from cdrtools
require.

Okay.

The lm kernel may not work with the scsi modules you need for the CD
burner. I compiled it to work only with scsi_mod and sd_mod, but the
burner needs ide-scsi and sr_mod and sd as well. The modules may still
insert even if the kernel was compiled with those lines as N instead of M
(no instead of module).

I will try to find time to add all of these modules into the kernel and
recompile.

I did that and uploaded bzimaglc.431 in ./2.4.31

If they are compiled in this saves room on the RAM disk. But the
machines which have the USB slots and CD burners do not belong to the
slower ones. I think it is not necessary to minimalize the kernel
too radically.

I was trying to fit into the existing 4MB RAMDISK.

You can add such a table to my blfiles.htm if you have time. Or post all
the 2.4.31 kernels at your site with better documentation. I will have more
time in February. I am now using the smf kernel on all my desktops, and the
lm on the laptops. They both support firewall.

No, your blfiles.htm has improved a lot. It is quite clear now.

Thank you for pointing out the confusion.

I will try to make you a custom kernel some time soon, with no need for
modules: support for cd-rom, cd-burner (ide-scsi, scsi_mod, sr_mod, sg) and
USB storage (scsi_mod, sd_mod, usbcore, ohci or uhci or ehci - do you know
which ones your computers needs?, and usb-storage).

I used to load

usbcore.o
uhci.o
usb-ohci.o
usb-uhci.o
usb-storage.o

These are all compiled into the kernel now. So are the cd-rom modules including sr_mod and sg, and I think also ide-scsi (for scsi emulation).
