------------------------------------------------------------------------------

 Function : Get a selector for the 1kb BIOS data area.

 Syntax   : USHORT BLXAPI DosGetBIOSSeg(PSEL biossel);

 biossel    Pointer to an integer to receive the protected mode selector to

 Return   : Selector for the BIOS data area corresponding to real mode
            segment 0x0040.

 NEVER be freed.

 Example:

    #include <stdlib.h>
    #include <stdio.h>
    #include <string.h>
    #include <blx286.h>
    void main (void)
    {
    SEL      biossel;
    /* Get selector for BIOS data area */
    if (DosGetBIOSSeg(&biossel) != 0)
       {
       printf("DosGetBIOSSeg() failed\n");
       exit(255);
       }
    printf("BIOS selector is : %04X\n",biossel);
    }
