on terminals with no pad char (cons25) and quote from tputs.c says so too:
! * Too bad there are no user program accessible programmed delays.
! * Transmitting pad characters slows many
! * terminals down and also loads the system.
more weird kinds of a.out than anyone can argue for. This code failed to
load the first 28K of the text-segment, in the case where the first page
of the a.out contains only the a.out-header, and the text is still at 0x0.
Thanks Steven !
been relocated to run in the 64k segment at 0x10000 with the stack at
the top of this segment. This corrects the problems machines with 512K
base memory had booting.
2. startprog routing rewritten to convert the BOOTSEG ss to a KERNELSEG
ss, this eliminated the last of the >512K memory references. Additional
cleanup in here included a better way to copy the arguments to the
kernel stack.
3. Elimination of argv and esym cruft saved a few bytes.
4. Only need to truncate the head.a_entry to a meg boundary once intead
of every time we used it! [Saving more bytes].
5. Addition of version 1 bootinfo structure support. These boot blocks
pass the kernel name in to the kernel now.
6. Removed historical comments about MACH argv stuff, as it is useless now.
that and when it does it will be done differently.
2. The kernel now does a frame setup on entry so it ``looks'' like a
real function call. This will be needed by future boot code and
debuggers.
3. Clean up stack offsets to all be in decimal and use %ebp when copying
parameters in from the boot code.
4. Implement version 1 of the uniform boot code passing mechanism with
support for kernelname passing and nfs_diskless structure passing.
5. Document the 3 different ways the kernel is called depending on what code
is calling it.
- register, registerd, and make_keypair don't compile (and are bogus anyway)
- don't forget to put back the obj directory when doing `kprog'
- while we're at it make the `kprog' commands overrideable from the command
line
- add a bootstrap target which does the following:
install includes
cleandir and obj
zap old version 4.0 shared libraries (these will screw the build)
depend all install
rebuild stuff in the main source tree which depends on kerberos
1. Make DEPENDS fully qualified, and not implictly assume relative
to ${PORTSDIR}. This allows more arbitrary dependencies to be
specified. This also means that DEPENDS= x11/foo needs to be changed
to DEPENDS= ${PORTSDIR}/x11/foo in any Makefiles. I'll try to do
these changes myself.
2. Add an option NO_DEPENDS to disable the automagic building of depended
ports.

- Allow PPP to run multicasts natively.
- Deal properly with lots of similarly-named interfaces.
- Don't sign-extend if_flags.
NB: the last fix (to rtsock.c) must be reversed when we expand if_flags to a
reasonable size.

cleaned up much of the cruft in this thing.
No printf's in the case where things go well.
Gzip-headers can contain filenames and comments (as long as they're
shorter than the page-size.)
I don't think we leak memory, in the "exec/aout" code. I'm not quite sure
about the inflate code yet, but I don't think memory is lost.
Q: Can I add a class M_GZIP to <sys/malloc.h> and bump M_LAST one up
without any thing else needing tweaking ?
