- On hp720 systems running 8.05 or 8.07 there is an unsupported ramdisc
- availible.
- The major device number is 9, the minor number is 0xABBBBB,
- where A has to be a unique number for every ramdisc, B is the size in
- 256 byte blocks.
- Be careful, the memory used by the ramdisc is no longer availible to
- the VM system.
-
- Example (512 KB):
-
- mknod ramdisc b 9 0x100800
- mkfs /dev/ramdisc 512
- mkdir /mnt
- mount /dev/ramdisc /mnt

- Hope that helps,
