Greetings gurus all,

I am using djgpp V2 beta4 and trying to come up with some home rolled
vesa code. I call vesa function 0x4f00 with __dpmi_simulate_real_mode_interrupt(...)
using the go32 transfer buffer. I get the VESA signature and version 1.2 fields back.
The problem is when I try to print the OEM string using the supplied far pointer. I am
using the line;

      c = _farpeekb(_dos_ds, (ptr>>16)*16 + (unsigned short)ptr);

I don't get the nice 'S' character as part of 'S3 Incorporated.....' when I
use the interrupts successfully in real mode with BC 4.0.

I have pulled the faq apart and done a search on the mail-archive but I can't seem
to find the answer. Help!!
