1. Melden Sie die CD-ROM an (mount cd-rom).
Beispiel: mount -t iso9660 /dev/scd0 /cdrom
2. Geben Sie folgende Befehlszeile ein(enter commandline):
dd if=/Corel/Boot/boot1440.img of=dev/fd0
3. Nach Fertigstellung der Startdiskette wird die Eingabeaufforderung
erneut angezeigt. Fahren Sie das System herunter und
starten Sie es neu bei eingelegter CD-ROM und Startdiskette.
Corel LINUX-Express-Installation wird ausgef�hrt(shutdown and boot from disk).
Hello all,
That is the readme that "causes" my CMOS-crash -(..) my short translation-
I mounted the cd-rom with mount /dev/hdb /cdrom and floppy with
mount /dev/fd0 /floppy then I typed
dd if=cdrom/Corel/Boot/boot1440.img of=dev/fd0
that leads to the bootdisk that causes the CMOS-crash.
Any thoughts?

I respond:
Your dd command differed from the dd command in the readme by putting cdrom
before /Corel. Were you supposed to cd /cdrom? What directory were you in when
you typed the ill-fated dd command? Was there a file system on the floppy
before you mounted it? Maybe factory-formatted for DOS? Maybe such a command
would be valid if you were in / directory (root)? Otherwise cdrom and dev would
have to be preceded by /. Without this leading /, paths and file names ought to
be invalid. You are not supposed to mount a diskette when preparing to write to
the raw device, as opposed to a file system.
I once crashed my CMOS by an errant program, running in (Borland) Turbo
Debugger. When I rebooted, I noticed beeping, and the hard drive was not
readable. I rebooted from drive A, ran CHKDSK /f (a disastrous error), which
trashed everything because the hard drive geometry was being read wrong. I then
found the correct hard drive type in the CMOS after trial and error, no more
beeping, had to reformat and reinstall everything: 40 MB hard drive with
MS-DOS 5. That CMOS crash happened again later, but this time I remembered to
reset the hard drive type correctly in CMOS, and I was able to reboot with
nothing damaged. Nowadays I believe the BIOS can autodetect hard drive
geometry?

I think he meant C:\DOS>del *ball.com
which would result in the deletion of all .com files.

I respond:
This is a bug in MS-DOS and DR-DOS, and I don't know about other DOSes, but OS/2
gets this correct. Only files whose names actually end in *ball.com would be
deleted. I did an experiment in an unimportant directory with ajunk.txt,
bjunk.txt and junkc.txt. dir *junk.txt only showed ajunk.txt and bjunk.txt,
and del *junk.txt left junkc.txt and another .txt file intact. Maybe IBM
PC-DOS 2000 gets this correct too?
