The device syntax is like this:
@example
@code{(@var{device}[,@var{part-num}][,@var{bsd-subpart-letter}])}
@code{(@var{device}[,@var{partmap-name1}@var{part-num1}[,@var{partmap-name2}@var{part-num2}[,...]]])}
@end example
@samp{[]} means the parameter is optional. @var{device} should be
either @samp{fd} or @samp{hd} followed by a digit, like @samp{fd0}.
But you can also set @var{device} to a hexadecimal or a decimal number
which is a BIOS drive number, so the following are equivalent:
@samp{[]} means the parameter is optional. @var{device} depends on the disk
driver in use. BIOS and EFI disks use either @samp{fd} or @samp{hd} followed
by a digit, like @samp{fd0}, or @samp{cd}.
AHCI, PATA (ata), crypto, USB use the name of driver followed by a number.
Memdisk and host are limited to one disk and so it's refered just by driver
name.
RAID (md), ofdisk (ieee1275), LVM (lv) and arcdisk (arc) use intrinsic name
of disk prefixed by driver name. Conflicts are solved by suffixing a number
if necessarry. Commas need to be escaped.
Loopback uses whatever name specified to @command{loopback} command.
For crypto and RAID (md) additionally you can use the syntax
<driver name>uuid/<uuid>
@example
(fd0)
(hd0)
(0x80)
(128)
(cd)
(ahci0)
(ata0)
(crypto0)
(usb0)
(cryptouuid/123456789abcdef0123456789abcdef0)
(mduuid/123456789abcdef0123456789abcdef0)

(md/myraid)
(md/0)

(host)

@end example
@var{part-num} represents the partition number of @var{device}, starting
from one for primary partitions and from five for extended partitions,
and @var{bsd-subpart-letter} represents the BSD disklabel subpartition,
such as @samp{a} or @samp{e}.
A shortcut for specifying BSD subpartitions is
@code{(@var{device},@var{bsd-subpart-letter})}, in this case, GRUB
searches for the first PC partition containing a BSD disklabel, then
finds the subpartition @var{bsd-subpart-letter}. Here is an example:
@example
(hd0,a)
@end example
from one. @var{partname} is optional but is recommended since disk may have
several top-level partmaps. Specifying third and later component you can access
to subpartitions.
The syntax @samp{(hd0)} represents using the entire disk (or the
MBR when installing GRUB), while the syntax @samp{(hd0,1)}
represents using the first partition of the disk (or the boot sector
of the partition when installing GRUB).
If you enabled the network support, the special drive @samp{(pxe)} is
also available. Before using the network drive, you must initialize the
network. @xref{Network}, for more information.
@example
(hd0,msdos1)
(hd0,msdos1,msdos5)
(hd0,msdos1,bsd3)
(hd0,netbsd1)
(hd0,gpt1)
(hd0,1,3)
@end example
If you enabled the network support, the special drives @samp{(tftp)},
@samp{(http)} and so on ars also available.
Before using the network drive, you must initialize the network.
@xref{Network}, for more information.
If you boot GRUB from a CD-ROM, @samp{(cd)} is available. @xref{Making
a GRUB bootable CD-ROM}, for details.
