How to list hardware in DOS?

You can use HWiNFO, available for DOS.

Hardware Info (HWiNFO) is a powerful system information utility designed especially for detection of hardware.

Download here(Look HWiNFO v5.5 for DOS).

SOLUTION-1:

There is a free tool from FreeDOS, which is very similar to 'lspci'. This tool should be compatible with MS-DOS. Download it from: http://www.ibiblio.org/pub/micro/pc-stuff/freedos/files/distributions/1.2/repos/pkg-html/pcisleep.html

And use it as:

pcisleep L

this will list devices on PCI bus...

addr vendor:type  vendor description
-----------------------------------
xxxx [8086:7111]  Intel  IDE Controller
xxxx [9999:9999]  AMD    LAN Ethernet
...

SOLUTION-2 (only for Network Cards on PCI):

There is a free tool, called 'nicscan.exe' which scans PCI for Network cards available. Donwload from here: https://www.jumpjet.info/Application-Software/DOS/Hardware/2/NICSCAN/NICSCAN.zip

nicscan.exe

it will list something like:

Bus: 2     Device: 0          Function: 0

PCI vendor: 1022 = Advanced Micro Devices [AMD]
PCI device: 2000 = 79c790 [PCnet32 LANCE]

The result shown above is the VMWare NIC AMD 79c790 10Mbps
