rhel5 via usb

So I’ve got my spiffy new HP DL360 G5 unboxed and pieced together and then I realize that they don’t come with CD/DVD drives in the low end package, something I should remember by now. That means the DVD of RHEL5.1 I’d burned yesterday to make sure I was ready, is pretty much useless. I know I can boot from a usb stick but I left the ones I’d made out at the facility, so now I have to dig up the instructions again and remember how to do it. So here they are (your locations may vary):

1. Insert RHEL5.1 DVD into laptop, it becomes /media/cdrom
2. Insert thumbdrive into laptop, it becomes /dev/sdb1 (/media/disk)
3. cd /media/cdrom/images/
4. dd if=diskboot.img of=/dev/sdb1
5. remove thumbdrive
6. insert thumbdrive in DL360 front usb port
7. boot DL360 and install from my share

Pretty damn easy really. Oh yeah, remember to copy anything you have off the thumb drive first or it will be gone.
