DOS ain't dead

Some time ago I wrote a small utility for gathering some info from ACPI BIOS. One of the important features is detection the number of physical and logical CPU cores.
I have a new processor (pentium E5300) which is effectively a Core 2 duo processor (with two physical cores).
The last version on the ACPItool misdetected it as a one physical and two logical cores. (in other words one physical and hyperthreaded).
So I modified the source a little bit.
Can you test it with your processors?
I am especially curious about Pentium 4 with hyperthreading procs.

No P4 to test, but here are the results on this Intel i7 quadcore
with hyperthreading enabled.

ACPI tools v 1.1c - created by Laaca (laaca@seznam.cz)

Physical processor cores: 4
Logical processor cores: 8

/r works to 'cold' reboot the machine.

/p does not work to power-off.

Ooops.
You are right. The shutdown does not work here.
I have completely forgoten that I made even version 1.2 with working shutdown and with ACPI timer detection.
So by mistake I updated the old 1.1 version.

Anyway - the archive is updated, now with version 1.2b.

AcpiTool 1.2b

DOS-u-akbar!

I just tested 1.1c on 4 machines:
a) Intel Core i7-3330, CPU-Z says: 4 cores / 8 threads
acpitool /c says phys 4 / logical 8
b) AMD Ryzen 5 5500, CPU-Z says: 6 cores / 12 threads
acpitool /c says phys 6 / logical 12
c) Intel Core i7 930, CPU-Z says. 4 cores / 8 threads
acpitool /c says phys 4 / logical 8
d) AMD Ryzen 7 3800, CPU-Z says 8 cores / 16 threads
acpitool /c says phys 8, logical 16 cores

acpitool was booted from a FreeDOS diskette with an USB diskette drive.

On my i7-2600K it detects #cores OK, 4/8, when I disable HT in SETUP, then got 4/4.

DOS gives me freedom to unlimited HW access.

Minor typo at acpitool /zf:
"Rezident" instead of "Resident"

An older AMD Turion 64X2 TL-60x2
reported physical 2 and logical 2 by acpitool.

Great!
Accordingly CPU world database it is correct.

I happen to have a Dell Optiplex 780 MT with a Pentium E5300. I also have other similar vintage Dell Optiplex 745 (Pentium D 945), 760, 790, GX620 with a Pentium 4 HT 630, and a GX270 with a Pentium 4. I'll give this a whirl for you on some of them.

My results for i5-8250u laptop:

Physical processor cores: 4
Logical processor cores: 8

Also, even with v. 1.2b, /r works for cold-boot but /p does not shut down the system, just says powering down system, and hangs, with manual power-off necessary (ctrl-alt-del) doesn't work, either to get out of this system hang.

I did some testing with 1.2b


Machine           - S/N     - CPU                   - Physical/Logical
----------------------------------------------------------------------
Optiplex 745 MT   - 8KJTBF1 - Pentium D 945         - 2/2
Optiplex 780 MT   - F7BN5M1 - Core 2 Duo E8400      - 2/2
Optiplex 780 MT   - 4J9C5M1 - Pentium E5300         - 1/1 (Multicore turned off in BIOS)
Optiplex 780 MT   - 4J9C5M1 - Pentium E5300         - 2/2 (Multicore turned on in BIOS)
Optiplex GX270 MT - 55HCT31 - Pentium 4 2.6GHz 0F29 - 1/1 (HT turned off in BIOS)
Optiplex GX270 MT - 55HCT31 - Pentium 4 2.6GHz 0F29 - 2/2 (HT turned on in BIOS)*
Optiplex GX620 MT - 1M82S81 - Pentium 4 HT 630      - 2/2*
----------------------------------------------------------------------
* These seem wrong.  I would expect 1/2.


Reboots and power off did not work on any of the machines. Just returns "Something went wrong." message.

I think this is a bad assumption. The Pentium E5300 is close to a Core 2 Duo E4700 though wikipedia seems to think Wolfdale Pentiums are more similar to Wolfdale Core 2 Duos. There seems to be a lot of software/hardware "castrations" to brand the processor as Pentium.

I thought that these "Pentiums" marked as E<something> are more or less same as Core 2 duos but they have smaller cache.

So does Intel ARK, it lists the E5300 as "formerly known as Wolfdale" why the E4400 is labeled "formally known as Conroe", i.e. first generation core-2.
