Query MicroChannel

Released Februar 2003

QUMC identifies the MicroChannel adapters in your system, planar subsystems and the planar. QUMC will reconstruct and show the current system configuration. QUMC can be used on DOS, OS/2, Windows 95/98 and Windows NT.

QUMC for Windows NT requires the MCPOS driver to operate properly. MCPOS must be started prior to the invocation of the program. By contrast, QUMC for DOS is a standalone DOS program and does not require any additional drivers or utilities.

QUMC for DOS is available for download. QUMC for Windows NT is included in the MCPOS download package.

QUMC Options

QUMCs supports the command line option -a to print and search in QUMC's adapter list. The option directs QUMC to print resp. search only and not identify any adapters. MCPOS need not be started or installed to use this option.

The program name of QUMC for DOS is qmcdos while the program name of QUMC for Windows NT is qumcnt. The examples below use the Windows NT name of QUMC but they are also valid for the DOS version, i.e. you can use the same options on DOS.

  • Enter qumcnt -a to list all adapters.

  • Enter qumcnt -a <pattern>, to search for the string <pattern> (no regular expressions!) in the adapter descriptions. Enclose the input string in quotation marks if it contains spaces.
For example, qumcnt -a "ibm mem" will list all adapters containing ibm mem in their descriptions.

Currently, QUMC queries always 8 adapter slots regardless of their actual number, although once the planar has been identified, the number of actual slots could be taken from the planar ID list. This behaviour is intentional.

Known Problems

QUMCNT Beta Release does not query the BIOS machine ID and identify the machine model, submodel and revision.

Please report any problems or bugs.

Acknowledgements

  • Tim Clarke made invaluable contributions on subaddressing and extended POS topics, sincere thanks.

  • The planar ID list has been kindly provided by Peter Wendt, sincere thanks.

  • David Beem enlightened the PS/2 Interrupts discussion and the machine and Intel CPU IDs, sincere thanks.

The adapter ID list of QUMC has been initially based on QCONFIG V2.22 (Apr 25 1995) N Couch / J Muir, Copyright (C) IBM Corp. 1989, 1994. The adapter ID list has been since extended with a number of adapters not contained in the QCONFIG list.
