Re: openbsd pen drive

["Sweetleaf" <sweetleaf@fastmail.fm>]

Ok, sorry for any confusion. I am not saying that cd0 the cd is important
to me, i am saying that i have noticed when booting from the /bsd on the
boot cd  and not a hd ..when my pen drive plugged in,, the pen drive is
brought up and recognized as sd0 after everything else has completed. So
when i installed openbsd, the computer was fully booted from the boot cd
and my pen drive was available to the installer as sd0 and installed on
this drive. So.. after the successfully install, i am booting my computer
from the pen drive via... the bios setting usb-hdd and the drive at this
point in the game is not sd0a it is hd0a. The boot loader finds the
hd0a:/bsd on the pen drive and loads the kernel in memory,,, then the
kernel starts probing and loading things and ssh is started etc.. Then it
gets to the point where it tries to mount sd0a for the root but cant
because the pen drive is not brought online as sd0a until after this so
it fails and panics. I Watched the order in events from booting the 3.4
boot cd and as mentioned the pen usb system whatever comes on line after
the kernel finds its root. Going on the latter i assume the reason my
kernel can not find its root of sd0a and panics is because it not
available at the time it tries to mount it,, so i need to bring up the
required usb stuff and pen ,, then mount the root= sd0a at the end as
then it would be available to the kernel.

Thanks marco, for the help

ps: i tried the -a option and that another reason i figured the above,
because the only options available for the "choose root prompt" is cd0 as
the kernel does not have the sd0 usb pen online and has booted far enough
to shed the computer bios of hd0a.
