Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Hello friends, a question from a total Linux novice.
I have just installed RH 8.0 (kernel version 2.4.18-14) in a dual boot setup with XP, using GRUB, on a Compaq Presario notebook. In order to proceed with the RH 8.0 install, I had to type "linux nofirewire noprobe nopcmcia" at the start of the installation, or else the installation would hang at (various) places. With "linux nofirewire noprobe nopcmcia," the installation proceeds seemingly smoothly.
Later, at the GRUB screen when I am logging on, I find that I also need to hit "a" and add the "nousb" kernel argument, or else the Linux boot will hang at "Initializing firewire controller (ohci1394)". With "nousb," I get "[OK]" at the "Initializing firewire controller (ohci1394)" line in the boot sequence, and proceed into RH without difficulty. However, of course my USB floppy drive is now unavailable! Does anyone know how I can at this point mount my USB floppy drive?? When I right-click on the RH screen and go to "disks," only the CDROM appears.
Any assistance anyone can give with this problem will be gratefully acknowledged.
Distribution: Red Hat Linux 9, FreeBSD 4.8, Knoppix 3.2
First, try getting Linux started as usual :
- Log in as root.
- Insert your USB floppy device.
- Type "dmesg".
at the bottom, do you see something like? :
Initializing USB Mass Storage driver...
usb.c: registered new driver usb-storage
scsi1 : SCSI emulation for USB Mass Storage devices
Vendor: Model: Rev:
Type: Direct-Access ANSI SCSI revision: 02
WARNING: USB Mass Storage data integrity not assured
USB Mass Storage device found at 3
USB Mass Storage support registered.
If so, make a mountpoint where we try to mount the usb device, like this : "mkdir /mnt/usb".
Then do "cdrecord --scanbus" (USB access in Linux 2.4 goes currently with a SCSI emulation subsystem).
Finally, try to mount the USB device with : "mount -t auto /dev/sda1 /mnt/usb/"
If you're having troubles, check if the proper modules are loaded :
"lsmod |grep -i usb"
(Check for "usb-storage", if this one isn't loaded do "modprobe usb-storage").
Upon typing "dmesg" I saw exactly the lines you wrote above. I then created the mount point using "mkdir," then did the "cdrecord --scanbus." When I used the mount command as you state above, I get a message saying that "/dev/sda1 is not a valid block device." I then did "lsmod |grep -i usb" and usb-storage came up ok. But I still get the "/dev/sda1 is not a valid block device" error.
Cropcircle... through trial and error, using what you outlined above, I was able to mount the USB floppy drive by changing "sda1" to "sda." Not certain why that made a difference, but it did! I don't have the notebook here so unfortunately I can't post the output of "cdrecord --scanbus," but the output from that command did not look abnormal.
However, I notice that I still cannot mount (or unmount) the USB floppy via the GUI (i.e. by right clicking on the RH 8 Gnome desktop and going to "disk" ...only the CDROM appears on the menu.) Is it possible to modify RH 8 so that mounting and unmounting of the USB drive can be done this way? How do I get the drive to appear on that GUI menu every time I log on?
