[Barrelfish-users] skb problems booting on x86_32: can't find Eclipse?

[Simon Gerber]

Hi Malte,

Looking at your menu.lst it seems that you missed the line

  modulenounzip /skb_ramfs.cpio.gz nospawn

when inserting the prefix of your tftpboot location.

I'd assume it should be

  modulenounzip /usr/groups/srgboot/ms705/barrelfish/skb_ramfs.cpio.gz nospawn
