Enabling DMA to primary IDE in Dell Power Edge 400SC,WIN2K

Hi all,

This is my first Pentium system (Dell Power Edge 400SC server, WIN2K, 2.8c P4,800fsb,1024 pc2700(dual mode enabled), DVD,CD-RW), that was a deal a few weeks ago. This is the same motherboard as the Dimension 8300, with the Intel 875P and 82801EB(ICH 5) chipset

See link for much more info: http://www.techimo.com/forum/t76547.html


I had a little bit of a time extracting/installing drivers manually, but after a reformat/reinstall (sometimes you just want to start from scratch), I'm pretty sure all drivers are in OK (no flags in device manager).

The problem is that although I have IDE 2 DMA enabled for the DVD and Cd-RW (device manager\IDE ATA/ATAPI controlers\ secondary IDE Channel ) and they are both working in Ultra DMA Mode, the Primary IDE channel will work in PIO mode only, which degrades performance.

The documentation refers to using "switches" to change settings(with command prompts, I believe), and I muddled my way through using one to extract needed install files (-A), but can someone shed some more light on this, if you think it may be a solution. Of specific interest is the -H<mode> switch, and how to use it. This flag enables DMA Mode for an IDE device.
-------------------------------------
The Intel(R) Chipset Software Installation Utility package
contains the following items:

File(s)
-------
INFINST_xxx.EXE -or- INFINST_xxx.ZIP
README.TXT, RELEASE_xxx.HTM

*** NOTE: Only the files that reference the currently
detected devices are copied to the system.

If the -A option is exercised, the files are
not copied to the <Windows>\INF directory.
See Section 4 for more information.


************************************************** **********
* 4. LIST OF AVAILABLE COMMAND LINE FLAG OPTIONS
************************************************** **********
The Intel(R) Chipset Software Installation Utility supports
several command line flags for various installation options.
All command line flags and parameters must be separated by a
space, except for the language code after the '-L' flag.

Due to the different distribution formats available for the
Intel(R) Chipset Software Installation Utility, the command
line flag syntax may vary:

1. Self-Extracting .EXE Distribution:
When installing this software using the .EXE
distribution, an extra '-A' must be appended to the
INFINST_xxx.EXE program call (i.e. INFINST_ENU.EXE -A)
in order to successfully pass command line parameters.

Note: The extra '-A' flag for the self-extracting .EXE
package is DIFFERENT from the '-A' command line flag
option described below, under Compressed .ZIP
Distribution.

Example: To extract INF files using the '-A' flag
described below, the installation program
should be invoked as follows:

INFINST_ENU.EXE -A -A (optional -P)

2. Compressed .ZIP Distribution:
When installing this software using the .ZIP
distribution, there is no need to append any extra
flags to the SETUP.EXE program call in order to pass
command line flags.

Example: To extract INF files using the '-A' flag
described below, the installation program
should be invoked as follows:

SETUP.EXE -A (optional -P)

Below is a list of all the available command line flags that
may be used with the program call. Note that the '-L' and
the '-S' flags MUST be specified at the end of the command
line flag list.

Flag Description
---- -----------
-? Help flag. Displays the list of available
command line flags. This parameter works in
the Interactive Mode only.

-A Extracts the INF files and README.TXT to
either "C:\Program Files\Intel\InfInst" or
the <Installation Path> directory specified
using the '-P' flag. The software will
NOT install these INF files to the system.
This flag can be combined only with the '-P'
flag option. All other options will be
ignored if the '-A' flag is specified.
This parameter works in either Silent Mode
or Interactive Mode.

-B Automatically reboots the system after
installation. This flag is ignored if '-A'
flag is specified. This parameter works in
either Silent Mode or Interactive Mode.

-H<mode>
This flag enables DMA Mode for an IDE device.

-L<LangCode>
Forces the InstallShield* user interface to
display the specified language during setup.
Note that there should be NO spaces between
'-L' and the 4-digit language code (see
below). This flag and the '-S' flag must be
placed at the end of the command line flag
list. This parameter works in Interactive
Mode only.

-NOLIC
This flag disables the license agreement
dialogue box during installation. This parameter
works in Interactive Mode only.

-NOREAD
This flag disables the readme display during
installation. This parameter works in Interactive
Mode only.

-NOWEL
This flag disables the welcome screen during
installation. This parameter works in the
Interactive Mode only.

-OVER ALL
This flag will update ALL INF drivers even if
third party drivers are currently installed. This
parameter works in Interactive Mode only.

-OVER FWH
This flag will update the Security drivers even
if a third party Security driver is currently
installed. This parameter works in Interactive
Mode only.

-OVER IDE
This flag will update the Storage drivers even
if a third party Storage driver is currently
installed. This parameter works in Interactive
Mode only.

-OVER SMB
This flag will update the LAN drivers even if
thrid party LAN drivers are currently installed.
This parameter works in Interactive Mode only.

-P <Installation Path>
Specifies the HDD location to which the INF
program files are copied. If this flag is
not specified at the command line, the
<Installation Path> directory is by default
assumed to be:

C:\Program Files\Intel\INFInst

If this flag is used without the '-A'
option, only README.TXT will be copied to
<Installation Path>. The directory name can
include spaces. In this case, however, a
pair of double quotes (") must enclose the
directory name. This parameter works in
either Silent Mode or Interactive Mode.

-S Runs the Installer in Silent Mode. No user
interface is displayed. This flag and the
'-L' flag must be placed at the end of the
command line flag list.

-SKIP<DevID>
This flag will allow one or more devices to
not be installed.
--------------------------------------------------------------------------

I've tried bios settings too, but no go. Is there a later bios to flash than A02? Should I install a WIN2K Service Pack? Ideas?

Thanks in advance.

-LC

A long thread that might be a good sticky for all of 400sc owners/or those considering

Thanks, JP. I forgot about that site.

Maybe this question is better asked there...

Wow, I finally got it taken care of. Can you believe it was something as simple as installing service pack 4 from M$.

Perhaps W2K needed instructions to handle the hyper threading technology...

I dont have much experience with w2k but seems I remember that even when you installed a dual cpu setup that you still werent really using the extra cpu until it was "activated" by whatever means (I cant remember).

Since hyperthreading basically makes the one cpu look like two...maybe it was a related issue that was somehow affecting the IDE.
