*PCE (IBM PC 5150) emulator (IBM PC DOS 1.00 <-- PC Tools 3.24 / IBM PC DOS 3.00 <-- System Speed Test 6.00)

*86box (x86 PC) emulator (IBM PC DOS 3.30 <-- PC Tools 4.11 / IBM PC DOS 3.30 <-- System Speed Test 6.00)

PC-Tools 3.24 runs on IBM PC DOS 1.00/1.10, but the version is recognized as 0.48.
I guess PC-tools 3.24 didn't be supported officially on DOS 1.xx

PC-Tools 4.11 doesn't run on DOS 1.xx (requires DOS 2.x or higher.)

More interesting is that PCE recognizes CPU ID as Intel 8088 correctly, but 86box (or PCEM) recognized CPU ID as NEC V20.

But you didn't test the PC-Tools 4.11/PCDOS 3.30 combo in PCE. Perhaps it would give "NEC V20" too?

Downloaded PC-Tools v4.11 from WinWorld Library.
Installed to PCem with PCDos v2.11
Ran PCSetup.com to install PCem to c:\pctools. No memory resident options selected.
Tried to run PCTools.exe.
FAILED!
"Packed file is corrupt" message displayed.

OK. The above test was done in a very early version of PCem 0.5 that I had IBMXT installed with PCDos 2.11.
I loaded PC-Tools v4.11 in PCem12 with MSDos3.3 and also with PCDos 2.11 and it ran with no problems both instances.
So it was the early version of PCem that created the failure.

I tested to run PC-Tools 4.30 / PCDOS 3.30 with 4.77Mhz. (IBM PC 5150 Rev.3 BIOS 640KB)

Also I tested to run PC-Tools 4.11 / PCDOS 2.00 with 4.77Mhz. (IBM PC XT 5160 Rev.0 BIOS 256KB)

Well, I wonder you really did confirm that I didn't test.
