Hi there,

I am interested in doing file operations from a CONFIG.SYS loaded device
driver at BOOT time to load configuration information.

It is obviously possible as QEMM'S LOADHI.SYS must read other device
drivers and the OPTIMISE command causes LOADHI to write statistics to a file.

What contortions are required to do this safely , and what limitations are
involved ( if any ) ?

Thanks in advance,
