Can somebody help Please???

[Tona Lee]

Hi all,

I'm a beginer programming in C, C++.

1st question:
Would anyone help me on how to write a uitility that detects(read) Harddrive BIOS and
returns the values such as size, cluster, sector, and track... The utility can run 16bits
under MS-DOS when it boots from floppy???

2nd question:
Have anyone ever written a utility; it can detects(reads) the NIC's MAC address. If you did
would you please let me know how it can be done??? It's also running under 16bits envnt.

Thank you in advance for your help...

Regards,
Tona Lee

Hi, Sometime ago I found this piece of C code on the net, don't remember now where; it wasn't written by me, the author is on the "header". It may be usefull to you.
