- the major number wasn't checked, so accesses beyond the end of bdevsw[]
were possible. Bogus major numbers are easy to get because `sysctl -w'
doesn't handle dev_t's reasonably - it doesn't convert names to dev_t's
and it converts the number 1025 to the dev_t 0x35323031.
- Driver d_psize() functions return -1 to indicate error ENXIO or ENODEV
(the interface is too braindamaged to say which). -1 was interpreted
as a size and resulted in the bogus error ENOSPC.
- it was possible to set the dumpdev for devices without a d_psize()
function. This is equivalent to setting the dumpdev to NODEV except
it confuses sysctl.
- change a 512 to DEV_BSIZE. There is an official macro dtoc() for
converting "pages" to disk blocks but it is never used in /usr/src/sys.
There is much confusion between PAGE_SIZE sized pages and NBPG sized
pages. Maxmem consists of both.
Not fixed:
- there is nothing to invalidate the dumpdev if the media goes away.
This reduces the benefits of the early calculation of dumplo. Bounds
checking in the dump routines is relied on to reduce the risk of
damage and little would be lost by relying on the dump routines to
calculate dumplo.
- no attempt is made to stay away from the start of the device to
avoid clobbering labels.
Fix wrong && anachronistic comment about the type of bootdev.

many times" panics and perhaps other strange inconsistencies on NFS servers.

Dont gzip boot_crunch. (This SAVES space on a 4 MB machine, since the

This (with the kzip patch) makes a 4M machine boot and run again.

I will look at tgz'ing the help files, we need that.
Add a NOMAN= . It doesn't have a manual page yet.
Please don't cry :-). I ask Rod first. the whole isdn subdir is not
used in the moment and is only dead source code in the tree.
Add Bt956 as being supported.

Anyone with a new feature or driver in 2.0.5 should think about adding "blurbs"

this document needs some rounding out.
LINT talks about about 2.1. I changed that to 2.0.5,
and clarified why certain devices need "at scbus?".
There is still a crazy "PCVT=210" which shouldn't be there,
but corrected comment as it is needed for 2.0.5.

The final check is backwards or something so it always said it failed,
