25. program applications and download programs into the ADAM 4500 controller Additionally it points out limitations and concerns of which you should be aware 3 1 Programming The operating system of ADAM 4500 is ROM DOS an MS DOS equivalent system It allows users to run application programs written in assembly language as well as high level languages such as C or C However there are limitations when running application programs in the ADAM 4500 In order to build successful applications you should keep the following limitations and concerns in mind Mini BIOS Functions The ADAM 4500 provides only two serial communication ports for connecting peripherals so the mini BIOS of ADAM 4500 only provides 10 function calls Since the user s program can not use other BIOS function calls the ADAM 4500 may not work as intended Additionally certain language compilers such as QBASIC directly call BIOS functions that are not executable in ADAM 4500 The ADAM 4500 mini BIOS function calls are listed in the following table Function Subfunction Task 07h 186 or greater co processor esc instruct 10h Oeh TTY Clear output 11h Get equipment 12h Get memory size 15h 87h Extended memory read 88h Extended memory size cOh PS 2 or AT style A20 Gate table 16h 0 Read TTY char 1 Get TTY status 2 Get TTY flags 18h Print Failed to BOOT ROM DOS message 19h Reboot system tah 0 Get tick count 1 Set tick count 2 Get real time clock 3 Set real time clock 4 Get
