Installing Slackware 10.1 to USB HD
Ok, I'm a bit of a Linux newbie so bare with me. My plan is to take my old hd and use it as a usb device (using a Mapower KC31x Series External Enclosure) and install Slackware 10.1. I've googled some on usb and Slackware but the results I'm getting is mind bending. I can't read through all this articles. Sorry, I know this has been done before, but I need some help...

First off, my BIOS supports booting from USB device, so there shouldn't be any problem there. This is pretty much what I do:

1. Boot from the Slackware Install CD. I use "bare.i pci=biosirq noieee1394". The "pci=biosirq" is there to make Slackware find my usb hd, otherwise I get an irq error. "noieee1394" is to disable Firewire and start up a bit quicker.

2. Once logged in as root, my dvd-roms are mounted as /dev/hdc and /dev/hdd. I don't seem to be able to find my non-usb hd (which should be mounted as /dev/hda or /dev/hdb) for some reason. Anyway, I expected to see the usb hd mounted as /dev/sda, but there is no /dev/sda! In fact, there is no /dev/sd* at all...

Where is the usb hd device? /dev/what-where?

Running cat /proc/bus/usb/devices I see the following:

P: Vendor=0000 ProdID=0000 Rev= 2.04
S: Manufacturer=Linux 2.4.29 ehci_hcd
S: Product=PCI device 1002:4373 (ATI Technologies Inc)
S: SerialNumber=00:13.2

(Yeah, the usb hd already has Linux on it, but I want to reinstall it).

Oookay, lets have a look at dmesg:

usb.c: registered new driver usbdevfs
usb.c: registered new driver hub
PCI: Assigned IRQ 3 for device 00:13.2
PCI: Sharing IRQ 3 with 00:13.0
PCI: Sharing IRQ 3 with 00:13.1
ehci_hcd 00:13.2: PCI device 1002:4373 (ATI Technologies Inc)
ehci_hcd 00:13.2: irq 3, pci mem f8825000

lsmod gives:

usbcore 58892 1 [usb-storage hid usbkbd usb-ohci ehci-hcd]

To me, it all seems like the usb hd is found and everything is ok. But why isn't it in /dev?
