Re: Transfer .iso to USB flash

["Nicolas Thauvin" <nico%orgrim.net@localhost>]

Hello,

You can have a look at this script
http://ftp.netbsd.org/pub/NetBSD/misc/jmcneill/mkmemstick.sh to transform
a netbsd ISO image to an USB image.

It requires a NetBSD system to run (to install the NetBSD bootloader) and
sysutils/cdrtools from pkgsrc.

$ sh mkmemstick.sh i386cd-5.0.1.iso i386memstick-5.0.1.img

Then dd the image on your USB stick

Hope this helps.
Nicolas
