This problem does not occur in older models of Advantech, may be is a
special case.

I try with BUF 40, works fine and cuts compilation time in half,
amazing!.

XMS allocated 10.00 MB, driver size with tables and stack: 15147 bytes.

I need to learn more about freedos, thanks for your tips.
Many years out of DOS.

It is an industrial computer, an ISA backplane, all-in-one computer in
an ISA card. Small size, very rugged case, no fans in the motherboard,
hard watchdog,very fast boot, supports VGA/LCD. The disk is a removable
solid state SanDisk 64 Mb. 

It runs a program that controls a machine for fruit processing with two
custom-made ISA cards to interface. Memory Mapped I/O and interrupts.

Thanks for your excelent work and support.
