how it is possible to check whether nic card is present or not from pure dos?
need c or c++ or assembly code to check whether the card is present or not

Detecting a Network Interface Card from DOS can vary from brand to brand.  It can also vary by the type of NIC (PCI, ISA, USB, PCMCIA, etc.).  Are you trying to detect a specific card or just see if there is one present?

hello tripleFault,

i need whether on card is present or not? then need to identify which card it is like details of the card...

if any idea please reply

with luv

It *really* depends on the type of bus you're wanting to scan. If it's PCI then you just do some PCI PNP detection and compare which device you find against a list like the one at http://www.yourvote.com/pci/

hai chase,
i am going through the url you have specified. but where is this details "PCI device listing" stored in computer. can we able to read the details through our own writte c or assembly program

luv

Use PCI to scan for any device of base class=2, sub-class=0 (Ethernet). Actually, you could just scan for class=2 to include Token Ring, FDDI, ATM, etc.

By "Use PCI" I mean either:
- INT 1Ah AX=B101h (for 16-bit real-mode code)
- PCIBIOS (for 32-bit pmode code)
- Type 1 direct accesses to the PCI hardware (16-bit or 32-bit code)

If you want to check if a specific Ethernet card is present, scan for
the PCI ID of that card.

It might be possible to do something similar for PnP boards (16-bit ISA) too,
but I'm not sure.

hai Chris Giese,

i have tried the url you specified.
and i tried the program pnp16.c with the list provided but it is not showing the Network Controller or something related to that.

what i need is to find whether NIC card is present in the system.
and interrupt 1A ax=b101h is not showing network control in it output list

and i have tried the same int 1ah with ax=b102h but it is need to give the vendor id and device id then as return cf set on error and clear on success.
but for that i need to give the specific id of both vendor and device but it may varry system.

so what should i do for getting whether the NIC card is present or not in a PC form pure dos through my own program.

any way thanks for the suggestions

bye

dear chris giese,
thanks a lot...
the "pci16.zip" file is listing all the vendor id, device id and no. but again need the device class ie. like network controller etc.

any way thanks a lot once again.

luv,

chaand
