As mentioned in the preceding list, you can use a hexadecimal device number in the root parameter. The device numbers are assigned depending on the type of device.
For floppy disk drives, the numbers are assigned starting with 200: /dev/fd0 is 200, /dev/fd1 is 201, /dev/fd2 is 202, and so on.
Hard disks have numbers assigned depending on the type of device.
For most hard disks, the numbers start at 301 (not 300 because there is no /dev/hd0): /dev/hda1 is 301, /dev/hda2 is 302, and so on.
When a second hard drive is used, the numbers jump to 340: /dev/hdb1 is 341, /dev/hdb2 is 342, and so on.
For /dev/sda devices, numbering starts at 801: /dev/sda1 is 801, /dev/sda2 is 802, and so on.
The second hard drive starts at 811: /dev/sdb1 is 811, /dev/sdb2 is 812, and so on.
Because floppy disk and hard disk drives are usually the only devices that can act as a boot devices, these numbers should suffice for all occurrences except removable media.
