Hi!

Does anyone know if there is a real time library or kernel/BIOS
for 386-PC that interfaces to Turbo C++.

What we want to do is:

   1. Keyboard I/O
   2. Screen I/O
   3. Disk I/O (if possible)

And always be able to respond to hardware interrupts (IRQ9-IRQ11)
within 5 micro seconds or about one hundred clock cycles.

That is: The I/O routines must be reentrant and never diable 
interrupts more than a few micro seconds.

Best regards,
Jonas

PS. Please don't use reply! The return path is not correct!
    Please send the letter directly to the internet address.
