assistant: In a message dated 05-09-98, Anthony Tibbs said to Murray Smith about Ide
"sleep" Mode
Hi Anthony & Murray,
The DosDevIOCtl() API is what is used in place of port I/O and BIOS
interrupts under OS/2.
Actually, "indirectly" will do.
Provided the device driver for the device in question supports the I/O
control needed to spin the drive down, all will be fine. It is simply a
matter of coding the subroutine call into the kernel.
If the drive were a SCSI, one would simply send the ASPI command sequence
through the ASPI driver and that would be it. However, IDE is a cheap kludge
and frequently works like one, especially when it comes to specialised,
low-level programming. As a result, YMMV.
I don't have any IDE drives here, but I do have the full OS/2 Warp 4
Developer's Toolkit. I can research the matter in the documentation, but I
cannot test any code for IDE drives on my all-SCSI system.

Hi Scott,
Not so. The IDE paddle board is entirely "owned", so you have to play nice
[unless you are in ring 0].
No. There is no special privilege conferred with being run in CONFIG.SYS.
Only the kernel and device drivers get to run in ring 0.
The way to perform hardware manipulation is to issue IOCtl calls using the
appropriate API. It is documented.

Write your reply.

assistant: Hi Anthony,
I don't program in Intel assembly but I maybe able to help.
If the processor doesn't have any direct bit test instructions then this is
one way to do it.
    make copy of register.
    mask off all other bits except bit 6 using logic AND.
    test if register is zero if so bit is not set else set.
    restore register.
I'ld do this on a MC68k you will have to make the translation, assume d0 =
;
    move.l  d0,d1           * save register
    andi.l  #$40,d0         * mask off bits
    beq     .bitnset        * If zero flag set then bit not set
    bra     .bitset         * else bit set
.bitnset
.bitset
    move.l  d1,d0           * restore register
You could save a cycle or so by masking and testing the saved register and
therefore eliminating the need to restore.

I never haerd about this...
Perhaps if you update the registers one by one it could cause problems to
do this for all 768 registers.
But if you move the whole block of 768 bytes at once there should be no
problem to do it during the retrace.
btw: even on new cards updating the color registers NOT during the retrace
causes the screen to flicker (e.g. on my Hercules Thriller).
It's no problem to move 64k of data during the retrace (not even on ISA-
systems).
The worst thing that could happen if the system is too slow (8088) is that
the screen flickers.

assistant: Hm.. Are you absolutely sure there are no TSRs loaded?  In Ralph Brown's int
list, under the description of int 19h (bootstrap loader) it says:
"This interrupt reboots the system without clearing memory or restoring
interrupt vectors.  Because interrupt vectors are preserved, this
interrupt usually causes a system hang if any TSRs have hooked
vectors from 00h through 1Ch, particularly INT 08."
So maybe you should restore all interrupt vectors, just in case.  Actually,
anyone know why exactly it would crash if interrupt vectors haven't been
restored?  Anyone know why I can't step into int 19h in Turbo Debugger?

assistant: wait a minute.. you guys are talking about just changing the color values,
not the image. You can do that regardless of where the retrace is, because
nothing on the screen moves. you can't get it to flicker just doing that
unless you set them to black first. What makes a flicker is when the
background gets pasted and the sprite gets cut off for the retrace, then
suddenly appears the next time. that frame with the sprite missing is the
"flicker".

 try "resetting" the interrupt vector table, some of the vectors are

GUESS #2
 booting a hard disk is initiated by the MBR (stored with the partition

 with dos the MBR later execs the boot sector... so you need a MBR image to

assistant: Hello, thanks for replying.
        The bios is an Intel.  The markings on it are d27128a-2 and
        k8342410.  A dump of memory reports P. Rom Rev 1.03 8/24/88
        Copyright Seiko Epson. 1988.
        The clock calendar chip is not a Motorla as I said but still
        is a 146818.  I think that these were a common "Cmos" of the
        time but not common for XT class machines.  I still don't see
        the wisdom of having one if it's not programmable in the sense
        that an AT "Cmos" is.  I still have two banks of dips and
        the machine still won't recognize several of my cards without
        some duplicity on my part.
        While I had the hood up I looked to see which interupt chip
        that I have and couldn't find one.  This mobo has an Epson
        chipset and I think that this set takes care of several
        functions.  I say that because I also couldn't find a dma
        controller or an address bus controller.  The point, though,
        is now I don't know if I have the usual, for XT, 8 interupts
        or some other number that Epson pulled out of thin air.
        I appreciate any help that you can give me setting the clock
        calender chip with an assembly routine.  I have tried a lot of
        utilities to do it but I think that they are designed for AT
        class machines because none of them works.  Dos changes the
        time and date only until powerdown.  I've just changed the
        battery and it tests okay.
        P.S.  I plan to assemble the routines in a Debug Script if that
        makes any difference in what you need to tell me.
        Thank you for your time and consideration.

Hi 80xxx,
80xxx>While it's true that many of the BIOS services are no longer used,

Actually, they aren't important to OS/2. It requires p-mode drivers or
p-mode, IOPL-enabled DLL's for everything hardware related. There is no
r-mode execution under OS/2 (or NT).
80xxx>These include Advanced Power Management functions, 32-bit PCI

On many systems, the RAM copy of the BIOS is overwritten by OS/2, and
restored from ROM when it shuts down. The BIOS is replaced, unless one very
special device driver requests it remain. I know of nobody who still uses
that driver.
The same thing happens with NT.
OTOH, Windows 95 doesn't do this, as it allows real-mode execution. This is,
of course, because Windows 95 is just a GUI shell on top of MS-DOS 7. It
does permit p-mode hardware access for VxD's, but it still permits r-mode
hardware access too. Since Windows 98 offers no architectural changes, I
would expect it to remain this way too.

Write your reply.

assistant: Ok, I ran it.  Under Win95 when I rebooted into MS-DOS 7 with absolutely
nothing loaded (bypassed everything) LILO worked, and was able to boot Linux
but not Win95.  In my case, I'm guessing this has something to do with the
fact
that my Linux partition is on a physically different drive from my Win95
partition.  Presumably the original Win95 boot sector is placed somewhere
lse
(I don't really know how all this works) and it's not being loaded properly
r
something.
When I saved the boot sector from an MS-DOS 6.22 boot floppy and a formatted
non-boot floppy, the two seemed to be almost exactly the same, and the
bootable
image had "non-system disk ... etc".  When I ran them with your program, both
said the non-system disk message.  And it was a boot floppy, I rebooted and
used it and it booted MS-DOS 6.22 =P
I used the following code to read it:
    mov ah, 0 ; reset disk system
    mov dl, 0 ; drive a
    int 13h
    mov ah, 2 ; read disk sectors
    mov al, 1 ; num sectors to read

    mov bx, offset buf

    mov returncode, ah
outahere:
buf was just an array of 512 bytes.  And yes, buf was cleared before filling
it, and the code did actually read from the disk and fill the buffer. (carry
flag was not set).  Hmm.. I've prolly just done something really stupidly
wrong.

Actually, NOP is quite useful if you want to align your code/data, make
very short (inner) loops pair on Pentium-based systems, or just want
to delay execution for a very short time (like, after port access, or
something). NOP = XCHG AX, AX (both have the same opcode). Ridiculous:
NOP is uv-pairable on Pentiums, so two NOPs can be executed at the same
time on these machines. :)

That could be a good idea in an ISR (unless the compiler does it for you):)

Does your compiler set DS?
Is there any harm expressing it as IIR-THR :) for readability...
actually that op-code disables them
