Intel 273246-002 manual CE-Ready Windows CE Loader, Integrated Bios Debugger

BIOS Quick Reference

The software on the target can be any terminal emulation program that supports ANSI terminal mode, using 9600 baud, no parity, and one stop bit (Note: This can be modified by the OEM during BIOS adaptation.) The program must be set to not use flow control, or the console may seem to stall or not accept input.

Caution: HYPERTERMINAL’s default setting is to use flow control, which will render the console inoperative. To change this, create a new session, change the flow control setting to “none”, save the session, and exit HYPERTERMINAL. Then reinvoke HYPERTERMINAL with the session and it will operate with the new flow control setting.

5.10.2CE-Ready Windows CE Loader

Your system’s BIOS is “CE-Ready” and can directly boot Windows CE* without loading an intermediate operating system such as DOS and LOADCEPC. Instead, the NK.BIN file can be placed on a disk drive or drive emulator, and then the BIOS can be configured through the Basic CMOS Configuration Setup Screen to boot the NK.BIN file from the boot drives instead of the boot records on those drives.

To configure your system to boot Windows CE natively from a disk drive, set the “Boot Method” field to “Windows CE” in the Basic CMOS Configuration Setup Screen. Then, place a copy of NK.BIN suitable for execution by LOADCEPC in the root directory of your normal boot drive, such as drive C:. Then, reboot the system. The configuration box should be displayed (Figure 5-8), and immediately following should be the message “Loading Windows CE…” followed by a series of dots, indicating that the loading process is continuing. Once fully loaded, Windows CE takes over the system and runs using the standard PC keyboard, screen, and PS/2 mouse.

5.10.3Integrated BIOS Debugger

The system’s BIOS contains a built-in debugger that can be a valuable tool to aid the board bring- up process on new designs similar to the evaluation board. It supports a DOS SYMDEB-style command line interface, and can be used on the main console’s keyboard and screen, or over a redirected connection to a terminal program (see “Console Redirection” on page 5-9).
