It was funny to try to use my terrible Spanish .. and find half the local
people considered Spanish _their_ second language too!  The area was much
more oriented toward German and British tourists, so we Americans had to
convert whatever "English" we saw (menus, signs, etc.) into American :-)

Write your reply.

assistant: Hi..
There are no dates stored in the FAT.
The FAT is not itself a file!!
I think you mean a file's directory entry..???  The date of a file is stored
at offsets 24 & 25 in the file's directory entry.
Ok here's how the date is stored:
bits 0-7 are stored in byte 24, whilst bits 8-15 are stored in byte 25.
bits 9-15 are the year, less 1980 (ie 1980 = 0, 1981=1 etc).
bits 5-8 are the month, 1-12
bits 0-4 are the day, 1-31

assistant: Hi Peter,
are you aware that to get use of the linear frame buffer in vesa 2.0
you need to set the 14th bit in the mode id (0101h = 4101h) which
turns on lfb.
that looks about right.. but you mush load GS: with a value other than
zero. look here--:
;------------
mov ax, 068h        ; this is should be the selector you have setup.
mov gs,ax
mov edi, 30000000h  ; (destinatoin) this points to your linear frame buffer.
mov esi, xxxxxxxxh  ; (source)
; a note of caution - sting instructions rely on DS:(e)si & ES:(e)di
; only source allows segment overrides.
; another note to use the lfb you need to treat edi as if its memory!
; what i mean is you may need an address override like:
db 067h  ; <- address override
mov dword ptr gs:[edi],eax
add edi, 004h
insert draw,plot,line, fill code here!
;------------
what do you have for the selector your using in GS:  i.e.
size=  ffffffffh
base = 00000000h
dpl=   0
type=  data r/w
granualirty= 4kb
            ~~~~~~~~~
no chance :)
????
                                      ^^^^^^^^^^
that is the cause - no GDT setup -----^
                ~~~~~�~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
have a close look at | and there should be one such selector pre-fabed.

[Exception 6 & 7]
[...]
o

Well you're right.
Exception 6 and 7 are so called FAULTS. That means the address placed onto
the stack is the starting address of the initiating opcode.
You explained the exception 6 well, so let me add exception 7.
This exception is initiated
- when no numeric coprocessor is available or
- when a task switch occurred while a task was waiting for the fpu to show
   results and the new task wants to use the fpu, too.
In either case the saved CS:eIP on the stack will point to the beginning
of the fault causing instruction.
Hop it helps ...

C code would be off-topic here; there's some asm code in the 1993 80XXX
snippets.
I don't really have the specs either, but's here's what I know about the
format:
The first line is always:
begin <attributes> <filename>
The attributes are usually 644. They stand for the file's privilege
rights, and are usually only of any importance on Unix systems.
Each encoded line begins with the line length (+32 to make it printable,
usually 'M' for the regular 64-char lines).
For the rest, the uuencoder reads 3 bytes (24 bits) and writes them out as
4 bytes, each containing 6 bits and with 32 added to them to make them
printable.
The last input bytes are padded with 0's if necessary to make it 3 input
bytes. In most modern uuencoders, output spaces (ASCII 32, 20H) are
converted to the '`' character.
The encoded data ends with the single line "end". More complicated encoders
might add checksums or CRC values at the end, or they might add the ability
to break up the output file into pages or separate x-byte long files, etc.

That would be http://sunsite.unc.edu/pub/micro/pc-stuff/freedos/
You could also use a www.webcrawler.com for searching "freedos"
Try this
  locate the beginning of your command string your parsing
  copy it to a scratch buffer, nul terminate it
  convert all alpha's to upper case (as needed)
  scan for bytes < 21h or comma's, place a nul there if there is one
  you have nul terminated the seperate components
Parsing the components of the command string are a different matter.
There are three methods I can think of offhand.
It may be easier to look at it like this. Each item on the command line
is either a basic command, a value, or a variable. Determine what each
type that item may be and place them into a process_buffer. When the
whole line has been parsed. Then process the buffer. Known values will
be in the buffer. (where as, in source file it isn't)

Nonsense.  Absolutely _every_ undocumented mode I've ever seen was
specific to that card (or at least to cards using the same chipset.)
x-modes are generic to all VGA cards, and do not require SVGA.  While an
SVGA card may support the same resolution/bit depth/number of pages as
an x-mode, it's still NOT an x-mode if you set it via the BIOS.  To
remain an x-mode, it has to be available on all VGA cards, which means
you have to set the parameters by writing the directly to the registers
yourself.
    Later,
