As of DOS 5, there are only two rules which must be observed in the placement
of the two hidden system files:

(1) - The two files (IO.SYS and MSDOS.SYS for MS-DOS systems; IBMBIO.COM
      and IBMDOS.COM for PC-DOS) must be represented by entries in the
      first two slots of the root directory on the boot drive, in that
      order.

(2) - IO.SYS (or IBMBIO.COM) must occupy a single contiguous block of
      disk space, and must be stored on the disk in serial fashion (meaning
      that the lowest-numbered sector contains the fist 512 bytes, the
      next-higher sector contains the next 512 bytes, and so on until
      the file size (as recorded in the directory entry) is satisfied.

There is no longer a requirement that the files be located at the front
of the user area on the disk, and MSDOS.SYS (or IBMDOS.COM) may be 
stored in fragmented, noncontiguous disk sectors.

The reason for the remaining requirements is that IO.SYS (IBMBIO.COM) must
be read into memory by the boot sector program.  This program must fit
into no more than roughly 450 bytes (512 bytes minus the size of the boot
parameter block), so there is no room for code to search the directory
for the file's entry, and no room for code to chase a string of FAT
references as the file is read.

The boot program locates the IO.SYS entry in the directory, translates the
cluster number it points to into an absolute sector number (after applying
if necessary a correction for the starting address of a fixed disk
partition), and then blindly reads sectors beginning at that location
into memory until it has read enough 512-byte sectors to cover the size
of the file specified in the directory.

An easy way to make a disk nonbootable is to have some defragmenter program
"optimize" the root directory by sorting the entries.  If it does not
exclude the two magic files from the sort these files will be moved
elsewhere in the directory, and the first requirement noted above is
violated.

Somewhere in the string of DOS versions the loading of MSDOS.SYS was
relocated to a point after the DOS file system interface was available;
this is why MSDOS.SYS may be fragmented.  Or at least this explanation
is consistent with what I've seen; I have no access to the source for
DOS...unfortunately.

Subject: Recommendations for good Windows 3 SVGA board?
Date: Wed, 08 Apr 92 14:17:20 GMT
Organization:  o/~ Lime and limpid green, a second scene... o/~

Hi, having just recently added Windows, I was appalled by the slow 
turtle-like pace of my Oak Tech 512K SVGA board in 256 color 
resolutions.  Therefore, I am looking for some opinions from fellow 
netters in terms of what SVGA boards are good for use with Windows.
 
To meet my criteria, the board must not be prohibitively expensive; 
must be compatible with a wide range of applications (I'd be 
thrilled if it supported VESA, too; in fact I believe this is a 
must now that I have contemplated it); and must be FAST!  
 
Some may ask, "Well, what is fast?"  I will instead describe what 
is SLOW.  When in 256 color mode, in a modem program, with the 
screen updating each new incoming line of text at about 1 line ever 
1.5 seconds -- this is SLOW!  Especially since I am at 9600 baud 
and it seems like I have been relegated to using 300 baud once more!
 
Therefore if you know of a board that has output about the same as 
one would experience in DOS (speedy output) then by all means 
follow-up or send me mail.  If I get any replies (please!) then I 
will mail summaries to those who ask; if more than 5 persons ask 
I will post the summaries to the net in this newgroup (unless, 
Timo, this is in the wrong newsgroup?  If so I apologize!! :-).
 
Thanks,

The BASICA 4-byte real is *not* the same as the Turbo Pascal 4-byte real.
But it *is* quite similar to Turbo's 6-byte REAL!

I don't have code handy, but what you need to do is this:

BASICA value ABCD (A=MSB, D=LSB)
Turbo Pascal value BCDEFA (B=MSB, A=LSB, E & F =0)


So take the 4-byte from the assembly routine, move the MSB into the LSB
of a turbo real, move zeros into the two bytes before the LSB, and move
the remaining 3 bytes to the high end of the real.



The above is from memory of how I got a BASICA program to read Turbo
6-byte reals.

PC Mag had a review of a number of such packages recently and came out in
favour of Stacker with Superstor a close second. Either would suit your
needs, especially if you have a 386 so that the performance hit in
compression/decompression is low and you can load the drivers in the UMB
to avoid taking up precious low memory (if that is a concern to you).
I use Stacker on one of my drives and even in Windows I hardly notice
the overhead (this is on a 386/40).

Unless the BIOS has support for such, it is not *possible* to do what you
wish using "standard" MS-DOS. The problem is that all anybody has to do is
insert a floppy and boot off of *that*. Instant bypass of all your protection.

DR-DOS gets around this by doing odd things to the disk format and partition
info. This may cause problems with some utilities. 

Recent BIOSes have options such as letting you not allow booting from
floppy. Others have a "power-on password" option. Being in the hardware
these can't be bypassed without opening the computer. If possible, I'd
recomend getting a machine with this sort of BIOS (recent Compaq's have
both, recent AMI BIOSes have the "don't boot from floppy" option, some
Tandy's have the "don't boot from floppy" option as well as a "boot from
ROM copy of DOS" option.)

Easy, just boot off a D0S 3.3 (or later) disk and then use the
DATE and TIME commands. Starting with 3.3 (or maybe 3.2) they
set the CMOS clock on AT class machines. Before that they only
set the *software clock, not the hardware one.

Note that on a PC class machine, you'll need the set program that
came with the clock card.

	A friend of mine has a small Toshiba lap-top computer with 640k, 20M HD
and a single 3.5 floppy.  He bought a copy of SuperStor V2.0 from an Egghead
salesman who claimed that SuperStor would solve his disk space problems.  

	Has anyone tried this program on this type of system?  Can this
program be recommended for a novice user?

			Thanks in advance,
			Howard
