NAME
rdev - query/set image root device, RAM disk size, or video mode

SYNOPSIS
rdev [ -Rrvh ] [ -o offset ] [ image [ value [ offset ] ] ]
rdev [ -o offset ] [ image [ root_device [ offset ] ] ]
ramsize [ -o offset ] [ image [ size [ offset ] ] ]
vidmode [ -o offset ] [ image [ mode [ offset ] ] ]
rootflags [ -o offset ] [ image [ flags [ offset ] ] ]

DESCRIPTION
With no arguments, rdev outputs an /etc/mtab line for the current root file system. With no arguments, ramsize, vid-
mode, and rootflags print usage information.

In a bootable image for the Linux kernel on i386, there are several pairs of bytes which specify the root device, the
video mode, and the size of the RAM disk. These pairs of bytes, by default, begin at offset 504 (decimal) in the ker-
nel image:

by when, then, if, far you done man paging the rdev? after that? run grub-install and re-assign the right values.

never use a production machine/hard drive for the fidgity R&D, learning tips and tricks, most teach the tips and tricks, none tells about "TRAPS." this i learnt from svn upgrading my xorg in 2004 which just halted my work on a 80 gb hdd, just dedicated for RHEL 3.0 dev work!
