Howdy,

   I need to check the bios timer tick count located at 40:6c.  I couldn't
find a peek macro or function in the GCC libs, so I wrote the following
macros.  I think they're OK, but peekdw(0x46c) results in :
segmentation violation pointer 0x0000046c.
I assume that this location has been mapped somewhere else by go32, can someone
explain to me where I need to peek to get this info?  thanks...
steve
