Need Help on detected program?

[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 Tona,

I'm not sure I understood your 1st question right, but if so try e.g. for drive "c:":

CString sDrive = _T( "C:\\" );
DWORD dwSectorsPerCluster; // address of sectors per cluster
DWORD dwBytesPerSector; // address of bytes per sector
DWORD dwNumberOfFreeClusters; // address of number of free clusters
DWORD dwTotalNumberOfClusters; // address of total number of clusters

isOk = GetDiskFreeSpace(
(LPCTSTR) sDrive,
&dwSectorsPerCluster,
&dwBytesPerSector,
&dwNumberOfFreeClusters,
&dwTotalNumberOfClusters );



The _T( ) is neccesary for me because I have to fight with UNICODE (it's a hard fight).
But it also works if you do not use UNICODE. The _T and also LPCTSTR are defines which are set to the corresponding function/type.
