RDEV(8) Linux Programmer's Manual RDEV(8)
NAME
rdev - query/set image root device, RAM disk size, or video mode
SYNOPSIS
rdev [ -rvh ] [ -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, vidmode, 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 kernel image:
498 Root flags
(500 and 502 Reserved)
504 RAM Disk Size
506 VGA Mode
508 Root Device
(510 Boot Signature)
rdev will change these values.
Typical values for the image parameter, which is a bootable Linux kernel image, might be:
/vmlinux
/vmunix
/boot/bzImage-2.4.0
/dev/fd0
/dev/fd1
When using the rdev command, the root_device parameter might be something like:
/dev/hda1
/dev/hdf13
/dev/sda2
/dev/sdc4
/dev/ida/c0d0p1
One may also specify the device by a comma-separated pair of decimal integers major,minor.
For the ramsize command, the size parameter specifies the size of the RAM disk in kilobytes.
For the rootflags command, the flags parameter contains extra information used when mounting root. Currently the only effect of these
flags is to force the kernel to mount the root filesystem in readonly mode if flags is non-zero.
For the vidmode command, the mode parameter specifies the video mode:
-3 = Prompt
-2 = Extended VGA
-1 = Normal VGA
0 = as if "0" was pressed at the prompt
1 = as if "1" was pressed at the prompt
2 = as if "2" was pressed at the prompt
n = as if "n" was pressed at the prompt
If the value is not specified, the image will be examined to determine the current settings.
OPTIONS
-r Causes rdev to act like ramsize.
-R Causes rdev to act like rootflags.
-v Causes rdev to act like vidmode.
-h Provides help.
BUGS
The rdev utility, when used other than to find a name for the current root device, is an ancient hack that works by patching a kernel image
at a magic offset with magic numbers. It does not work on architectures other than i386. Its use is strongly discouraged. Use a boot
loader like SysLinux or LILO instead.
HISTORY
At offset 502 there used to be the device number of the swap device (in Linux 0.12), and "rdev -s" or "swapdev" would set this. However,
since Linux 0.95 this constant is not used any longer, and the swap device is specified using the swapon() system call.
