  • 1. Mounting a digital camera
    Hello list, I'm looking for a little help mounting my usb mass storage digital camera on my RH 8.0 machine. I'm using the 2.4.20-28.8 kernel, and the last bit of my dmesg output says: "Initializing USB Mass Storage driver... usb.c: registered new driver usb-storage USB Mass Storage support registered." When I type the following: "/sbin/modprobe usb-storage; mount -t vfat /dev/sda1 /mnt/camera; /etc/rc.d/init.d/usb start;" I get: mount: /dev/sda1 is not a valid block device bash: line 2: /etc/rc.d/init.d/usb: No such file or directory So my questions are: (1) What does the "valid block device" error mean? How can I correctly mount my camera? (2) What is the correct command to start usb? Sorry if these questions are totally banal, I am new to all this. Any helpful replies most gratefully appreciated. best wishes Colin Cotter
  • 2. Random reboots
    Hi, Can a graphics card force a random reboot? I am experiencing occasional reboots since I switched to an nVidia MX 440-based board in June. I am using the most recent nVida driver - the same fault was present under the previous driver. Thanks, Geoff

Perhaps you should start playing around with your modules. During the boot
process of course no cdrom can be recognized. If your kernel is completely
modulized try to unload the floppy module (rmmod floppy) after your Linux
is up and running, change the floppy with the cd drive and load the ide cd
driver by (modprobe ide-cd). Check out dmesg for new messages...

Regards, Joerg.

Thanks. I just tried. rmmod floppy says that module is not loaded.
lsmod doesn't show anything that looks like floppy (or cdrom). So I
change floppy to cd drive. modprobe ide-cd works. lsmod now shows

ide-cd    33608    0
cdrom     33696    0 [ide-cd]

But mount -t iso9660 /dev/cdrom /mnt/cdrom still throws the not a
valid block device error.

1.first time install: laptop, no floppy and a bum CDROM drive

I have an older thinkpad that I would like to install redhat on.  It
has no floppy and if I remember correctly, the CDROM drive isn't
bootable(IE: If I put a win2k instal disk it doesn't read it.  I have
changed teh boot order)

I do have a little converter that will allow me to connect my laptop
HDD to my PC.  With that said, is there anything that I can do to
install it that way or does it need to be located on the target
machine?

Also, it's possible that the CDROM drive isn't as lame as i think it
is, it may just need a driver, do you have any suggestions?

The laptop currently has win2k pro installed, can I install redhat from
windows?  Sounds crazy, but maybe that is something that I could try?

I'm new to all of this and could use any pointers that you may have.

Thank you,
Steve

2.Laptop installation without cdrom or floppy ?

I have an old laptop which has a cdrom and a floppy, however  I cannot 
boot off either of these but they both appear to operate ok once an OS 
is loaded.  :-(

There are existing FAT32 and Slackware partitions on the HDD.

Is it possible to copy the FreeBSD /bin etc to the HDD Fat32 partition 
and then install FreeBSD from the HDD without using the cdrom or floppy 
until /stand/sysinstall ?

thanx

3.boot up dell latitude with no CDROM or floppy

I have a Dell Latitude L400 that doesn't have either a CDROM or a
floppy drive. It has win2K installed on it, but no one remembers the
password (which is why it was given to me) so i'm unable to load
windows.   I bought an external USB cdrom and an external USB floppy
and winXPhome - hoping that i would be able to bootup from either of
those devices and reinstall windows. I tried booting from the cd -
didn't work - same with the floppy, it doesn't see it.
Is there any way to either get around the win2k logon, or do a network
boot, or somehow get into the computer so i can install windows and
salvage the laptop?
any ideas would be greatly appreciated. tx.
