I am attempting to convert this function:
int ShowXpressRomInfo()
{
    unsigned char far * pBIOSTable = (unsigned char far *)0xF0000000L;
    unsigned char xpressStart[12]=
{'X','p','r','e','s','s','S','t','a','r','t',0};
    unsigned char xpressInfo[250];
    int x = 0;

    // Get BIOS Info Table
    do
    {
        if (_fmemcmp((unsigned char far *) &xpressStart,\
                     pBIOSTable,\
                    _fstrlen((unsigned char far *) &xpressStart))== 0)
        {
            pBIOSTable+=12;
            break;
        } else pBIOSTable++;
    } while (pBIOSTable <= (unsigned char far *) 0xF000FFF3L);

    I modified it to this:
int ShowXpressRomInfo()
{
    unsigned char * pBIOSTable = (unsigned char *)0xF0000000L;
    unsigned char xpressStart[12]=
{'X','p','r','e','s','s','S','t','a','r','t',0};
    unsigned char xpressInfo[250];
    int x = 0;

    // Get BIOS Info Table
    do
    {
        if (memcmp((unsigned char *) &xpressStart,\
                     pBIOSTable,\
                    strlen((unsigned char *) &xpressStart))== 0)
        {
            pBIOSTable+=12;
            break;
        } else pBIOSTable++;
    } while (pBIOSTable <= (unsigned char *) 0xF000FFF3L);

    But I get a segment violation when attempting to do the memcmp.
Any advice would be appreciated.
