assistant: Replying to a message of Ed Beroset  to All:
Have you actually done this? If this is at all possible, then why do we need
DPMI? Why was it invented in teh first place? All you'd have to do in DOS is
switch to protected mode, make a few selectors in the first meg of memory,
with memory limits as large as you like, and switch back to "real" mode using
the base values of those selectors as your segment register values.
It's a lot more than that; you didn't quote the real->protected switch, in
which it clearly states the segment register values are unchanged during a
mode switch. You have to create new selectors based on the contents of the
segment registers (which are 20-bit addresses), and forget that any of the
previous selectors even exist (because you can never find out what they are,
much less what info they contain).
No, it is not clear, not at all.. again, if this is possible, then why have
DPMI at all?

Windows, and OS/2.  Any program with any kind of memory addressing, calls, or
jmps, is going to be a REAL pain to write and maintain in straight machine
code with a hex editor, which is why we have assemblers.  You could try this
little five byte file though, enter the following hex codes into your hex
editor and save as BOOT.COM:
EA F0 FF 00 F0
DO NOT run this from within a multitasker, and if you're using any disk cache
with write-behind caching be sure to flush the cache before running this, it
jumps into your BIOS to reboot the machine.

huhu, it's my turn ;)
To get a linear buffer you just have to Set Bit 14 in Bx.
For Example:
   mov ax,4f02h
   mov bx, 10Eh           {320x200x64k }
   add bx,100000000000000b {set Bit 14}
   int 10h
Now, the offset of the screen isn't at A000h! You have to get the physical
address of it.
 mov ax,4f01h
 mov cx,10eh   {320x200x64k}
 xor di,di
 int 10h   {write ModeInfoTable to es:di}
At offset 28h of this table there will be a dword with the physical address

VESA was designed for real mode, 20-bit addressing.  I'm not sure it is set
p
to make a linear buffer for you.  However, if yoy know how much total memory
you have, and how much video memory you've got, you should be able to tell
Watcom to set up a selector at a specified absolute address.  I've got 16MB
f
total RAM, and 1MB of VRAM, so I'd set the address as 00F00000 (if I had
Watcom).

assistant: *** Tim Hutzler wrote in a message to Scott Mcnay:
The BIOS must be used, obviously. to boot up, but it's my understanding that
once an operating system goes into protected mode, it uses it's own drivers
and ignores the BIOS, in general.  It may use it for something like video
mode switching, but it has to drop back to real mode for that, and a
real-mode virus would get cut off again as soon as the system switched back
to protected mode.  A paranoid OS author would check the real-mode interrupt
vector to ensure that it was still pointing at ROM code.
The VGA BIOS pretty much only supplies functions useful for text-mode
operation; graphics-mode operations provided by the BIOS are notorious for
being masochistically slow.  Much the same applies to other BIOS code; it's
used for boot-up initialization, but the OS will generally not recognize any
device that it does not have it's own driver for.
I prefer the option for selecting the boot device, where you can have the
system boot automatically from C, and ignore A.  The boot virus protection
interferes with certain programs, such as Win95.  The boot drive option is
what I use when I build a computer.  After my first time trying to figure out
why Win95 kept locking up while installing, I have avoided the virus
protection option.

If someone pulls your battery, you will know that someone got into your

CMOS failure message due to the CMOS being wiped, and you just plain won't
know for sure if someone wiped it or if the computer got zapped by a power

Someone could just pull the hard drive out and put it on another computer,
therefore, to be properly paranoid, you'd need the entire hard drive
encrypted.  You're begging for trouble when you start thinking along those
lines.
The U.S. Army defends against that kind of thing by using removable hard
drives.  You can buy mounting kits that fit in a 5.25" drive bay and will
hold a 3.5" drive.  When you're done with the computer, you turn the computer
off, unlock the hard drive, pull it out, and put it in the safe or other
secure area.
Several times, I've worked on computers and the entire computer was in a
secure area; I had to show my ID and a copy of the work order, and sign a
sign-in sheet in order to get in to work on the computer.  They would turn on
flashing lights so that everyone in the place knew that guests were present
who did not have proper security clearance.
