Subject: Re: how to look at files in *.img files From: Statux <statux@bigfoot.com> Date: Thu, 24 Aug 2000 16:54:20 -0400 (EDT) example for 1.44MB image file: dd if=boot.img of=/dev/fd0 bs=1440k You must be root (have full permissions for the floppy disk device) boot.img is the image file (or whatever it happens to be named) /dev/fd0 is your floppy disk drive bs=1440k says that the block size is 1.44MB. This option (for this exact application of dd) doesn't usually make a difference and can be ommited (from my experiences). Then just mount the disk: mount /dev/fd0 /mnt/floppy or however your system is set up. === Subject: Re: how to look at files in *.img files From: John Aldrich <john@chattanooga.net> Date: Thu, 24 Aug 2000 17:00:45 -0400 On Thu, 24 Aug 2000, Bret Hughes wrote: > How can I mount and look at the files contained in the > intallation images for redhat?

IIRC, it would be something like (and people, feel free to jump in and correct me if I'm wrong! <G>): mount -o loop -t vfat <imagename.img> <mountpoint> At least that's what I did. *shrug* John === Subject: Re: how to look at files in *.img files From: John Aldrich <john@chattanooga.net> Date: Thu, 24 Aug 2000 17:04:07 -0400 On Thu, 24 Aug 2000, Statux wrote: > example for 1.44MB image file: > > dd if=boot.img of=/dev/fd0 bs=1440k > > You must be root (have full permissions for the floppy disk device) > boot.img is the image file (or whatever it happens to be named) > /dev/fd0 is your floppy disk drive > bs=1440k says that the block size is 1.44MB.

However, I did notice he said he wanted to do some upgrade installs on floppiless machines.... :-) John === Subject: Re: how to look at files in *.img files From: John Aldrich <john@chattanooga.net> Date: Thu, 24 Aug 2000 18:24:06 -0400 On Thu, 24 Aug 2000, Bret Hughes wrote: > > Thanks.

You'll need to use dd to copy to a floppy, though, as the previous person said. Then mount it as type vfat or msdos (I typically use vfat, since it covers both fat16 and fat32.) OTOH, if you don't want to write it to a floppy, my instructions will be what you want to use. :-) John ===
