Hi!
Could anyone see what's wrong with this code? I get the information correct
but it's something wrong and I don't know what.

Here's the code:
unsigned short modes[100];
getmodes(vbeinfo.videomodeptr, modes, 200);

void* getmodes(unsigned int modeptr, void* dest, int maxlength)
{
   int offset = (modeptr>>12 & 0xFFFF0) + (modeptr & 0xFFFF);
   dosmemget(offset, maxlength, dest);
   return dest;
}

And the struct:
struct VBEINFO {
  char vbesignature[4]; // VBE Signature
  unsigned short vbeversion; // VBE Version
  unsigned int oemstringptr; // Pointer to OEM String
  unsigned char capabilities[4]; // Capabilities of graphics cont.
  unsigned int videomodeptr; // Pointer to Video Mode List
  unsigned short totalmemory; // number of 64Kb memory blocks
  unsigned short oemsoftwarerev; // VBE implementation Software revision
  unsigned int oemvendornameptr; // Pointer to Vendor Name String
  unsigned int oemproductnameptr; // Pointer to Product Name String
  unsigned int oemproductrevptr; // Pointer to Product Revision String
  char reserved[222]; // Reserved for VBE implementation scratch area
  char oemdata[256]; // Data Area for OEM Strings
};

Thanks for all help!
