tape drive. I traced it to sys/scsi/scsi_base.c where some code were added
to print the return values of the sense command. My tape drive returned a
extended flags value of 0x20, so the key that is the lower 4 bits, is 0.
The code uses "key-1" to index into a table and then the kernel go to never-
never land.
Here is a fix for this. Will somebody please apply it?

It boots FreeBSD from a running MS-DOS system.
It's compiled using some MS-DOS tools, but there is a binary
hidden in the uuencoded file. (Go ahead, flame me if you can come up
with a solution for the problem. Just saying "this is bad" doesn't count!)
Rod, you were right: one would have to deal with weird interfaces to the
memory managers, and it seems that Christian found them all, and made them
work.
Thanks Christian!

------------------
Hi Everybody!
This is version 1.5 of "fbsdboot", a program that allows you to boot a kernel
from a MS-DOS partition or a FreeBSD partition. This program runs using DOS.
It works with various memory managers (like EMM386, 386MAX) under certain
circumstances.
First, a FreeBSD kernel is always loaded to memory starting at 0x100000. To
assure that loading the kernel *does not* overwrite memory used by memory
managers, high memory for the kernel is allocated and after loading the kernel
it's moved to 0x100000.
Second, there are many ways to switch to protected mode which is necessary to
start the kernel. Each BIOS gives you the possibility to use INT15H (AH=89H)
to do that. But some memory-managers like 386max does not allow you to use
this method.
An other way to do the switch is to use DPMI services, but they do not
guarantee, that the protected mode application is executed with privilege
level 0. Therefore this method is *not* used.
VCPI services offer another way to switch to protected mode, and VCPI servers
are built into "emm386.exe", "386max" and "qemm". That's why, this method is
implemented in fbsdboot.exe.
Fbsdboot.exe tries to switch to protected mode using VCPI services. If they're
not available INT15H is used to do the switch. If that fails, it's not possible
for this version of fbsdboot.exe to boot a kernel :-(.
You can get commandline options of fbsdboot if you start it with "-?" as option!
I don't know, if fbsdboot works with QEMM, as I don't have the possibility to
test it.
Enjoy and have fun!
Christian.

Make conditionals on BIOSWAIT consistent with usage in io.c.
If you had 'BOOTWAIT=0' in your /etc/make.conf then biosboot wouldn't
compile. It was '#if' in io.c and '#ifdef' in probe_keyboard.c so I
changed the latter to '#if'.
Even if BOOTWAIT is undefined then '#if BOOTWAIT' becomes
'#if 0' so it should compile either way with this change.
The "strings" program chokes if you try using "-n".

Try "strings -n SOMENUMBER SOMEFILE".

Here's a "diff -u" patch that corrects the problem.

expiration timer of anything which would expire later than that. (There
should be a way to call this from ip_sysctl() as well, but there currently
isn't.)
high load:
1) If there ever get to be more than net.inet.ip.rtmaxcache entries
in the cache, in_rtqtimo() will reduce net.inet.ip.rtexpire by
1/3 and do another round, unles net.inet.ip.rtexpire is less than
net.inet.ip.rtminexpire, and never more than once in ten minutes
(rtq_timeout).
2) If net.inet.ip.rtexpire is set to zero, don't bother to cache
anything.
Users-beware..
It is tested and working for me but probably have some bugs i
didn't noticed so test it and reply...
It can:
look at what's sent to the user from tty device
snoop on pty's,vty's and serial tty's
It (still) can't:
write to tty
see what user types in local echo mode
It is probably bad styled and
very dependant on tty_pty.c,sio.c and syscons.c
I would be really happy if another ppl would make their
changes because i am not sure this is the best snoop
we can have..but it is good..:)))))
I took 53 and it was too late when Jordan sayd
it better been 60..besides i have no clue how to make it 60..
Jordan- pleeease don't kill me..(This is also useful(??) device..)
