This is the virtual block driver for virtio. It can be used with
lguest or QEMU based VMMs (like KVM or Xen). Say Y or M.

There are two drivers for MFM/RLL/IDE hard disks. Most people use
the newer enhanced driver, but this old one is still around for two
reasons. Some older systems have strange timing problems and seem to
work only with the old driver (which itself does not work with some
newer systems). The other reason is that the old driver is smaller,
since it lacks the enhanced functionality of the new one. This makes
it a good choice for systems with very tight memory restrictions, or
for systems with only older MFM/RLL/ESDI drives. Choosing the old
driver can save 13 KB or so of kernel memory.
If you want to use this driver together with the new one you have
to use "hda=noprobe hdb=noprobe" kernel parameters to prevent the new
driver from probing the primary interface.
If you are unsure, then just choose the Enhanced IDE/MFM/RLL driver
instead of this one. For more detailed information, read the
Disk-HOWTO, available from
<http://www.tldp.org/docs.html#howto>.
