Chapter 5. DOS porting This section provides a summary of information and tips that will assist you in porting a DOS application from an IBM 4840-xx1/xx2. The IBM SurePOS 4851-514 was designed from a BIOS and software standpoint to be similar to the IBM 4840-xx2. This design allows for a simpler application porting process from the IBM 4840-xx2. Below are some of the differences in the drivers required to operate the IBM SurePOS 4851-514 in PC DOS 2000. Video driver - not required The video BIOS handles all video needs in DOS. Ethernet driver The SurePOS 500 Model 514 features the VIA VT8237 Ethernet Controller. You can download this driver from the IBM RSS support site. The ethernet package provides drivers for many common DOS network interfaces. Touch screen driver The SurePOS 500 Model 514 utilitzes the ELO resistive touch screen driver. Download this driver from the external website. You calibrate the touch screen during POST. To calibrate the touch screen: 1. Power on the system. 2. Enter BIOS setup by pressing the key during POST, or by tapping the touch screen twice when prompted during POST. 3. Select the Integrated Peripherals menu. 4. Set the Touch Calibration item to Linux/DOS. 5. Press F10 to save settings and exit the BIOS setup. 6. Allow the system to reboot. When prompted, tap the touch screen three times to invoke touch screen calibration. 7. Follow the directions on the screen. Serial ports The SurePOS 500 Model 514 provides six serial ports for connection to various I/O devices. Table 3 lists the serial ports allocations. Table 3.
