+===== Software =====
+The UAR/T used is a derivative of the Intel 8251 UAR/T so most basic code will run without significant modification. To use with MS-DOS on the SBC-188, TSR (terminate and stay resident) drivers are required to provide replacement BIOS functions (none of the BIOSes, including the latest BIOS-050, do not have any code to support the board). Additionally, most DOS programs assume that the serial and parallel ports live at specific I/O port addresses and are interrupt-capable. On versions of the SBC-188 prior to version 3, the interrupt system doesn't conveniently allow for interrupt-driven serial ports such as the 2S1P, so the 2S1P has to be run in “polled” mode. It's expected that version 3 of the SBC-188 will have a usable/trappable interrupt that can be connected to the 2S1P to allow for most software to work; the I/O port and interrupt selection allocation will still be an issue but that's easier to deal with.
+The software should be considered “beta” quality.
