  • Graphics Programming
    Operating Systems Development - Graphics 1 by Mike, 2010 This series is intended to demonstrate and teach operating system development from the ground up. Introduction Welcome! Wait, what? Graphics already? Thats right, we will start developing an ultra-cool GUI for the OS! :) Okay, not really, but its a start in that direction. This chapter is the first of a miniseries of chapters covering graphics programming. I plan to cover Vesa VBE, Video BIOS, and direct hardware programming for the VGA and, possibly, some SVGA concepts. I also plan on covering graphics concepts and rendering, including 2d vector rendering and images. Who knows; mabye a little 3d a little later. Excited? A lot of cool material coming up in this mini series spinoff of the OS Development Series! However, before we can dive into the wonderful world of computer graphics, we have to set up a ground rule. There are a lot of ways that we can work with computer graphics, and a lot of directions that we can take. Computer graphics are a complicated topic: It cannot be covered in one chapter. Well, it can. It would just be one .. very, very long chapter. Because of this, I decided to do this in stages. The first chapter covers working with graphics in real or v86 modes. We use the system BIOS interrupts and cover basic graphics concepts. The second chapter we will dive into Video BIOS Extensions (VBE) and Super VGA. The third chapter, will be the first chapter of a smaller miniseries covering direct hardware programming of the graphics pipeline: VGA and mabye some Super VGA topics.

  • Award BIOS Setup
    CHAPTER 3 Award BIOS Setup This chapter describes how to configure the BIOS for the system. 42 SBC-776 User Manual Starting setup The Award BIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it through the power-on self test (POST). When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage devices (hard drive, floppy drive, etc.). The BIOS launches the operating system and hands control of system operations to it. During POST, you can start the Setup program in one of two ways: 1.By pressing Del immediately after switching the system on, or 2.By pressing Del or pressing Ctrl-Alt-Esc when the following message appears briefly at the bottom of the screen during POST: TO ENTER SETUP BEFORE BOOT PRESS DEL KEY If the message disappears before you respond and you still wish to enter Setup, restart the system to try again by turning it OFF then ON or pressing the RESET button on the system case. You may also restart by simultaneously pressing Ctr-Alt-Del. If you do not press the keys at the correct time and the system does not boot, an error message appears and you are again asked to PRESS F1 TO CONTINUE, DEL TO ENTER SETUP Chapter 3 Award BIOS Setup 43 Setup keys These keys helps you navigate in Award BIOS: Up arrow Move to previous item Down arrow Move to next item Left arrow Move to the item in the left hand Right arrow Move to the item in the right hand Esc

    BIOS Settings Glossary Intel® Desktop Boards BIOS Settings Glossary The BIOS Setup program can be used to view and change the BIOS settings for the computer. BIOS Setup is accessed by pressing F2 after the Power-On Self-Test (POST) memory test begins and before the operating system boot begins. The presence of menus and BIOS settings are dependent on your board model, hardware components installed, and the BIOS version. If any problems occur (poor performance, intermittent issues) after making BIOS settings changes, reset the BIOS to default values: 1. During boot, enter the BIOS setup by pressing F2. 2. Press F9 to set defaults. 3. Press F10 to save and exit.

  • Booting Software from Flash
    ZFAN–12 1052 Elwell Court, Palo Alto, CA 94303 Tel: 800.683.5943 www.zfmicro.com Booting User Software from Flash Often, HW/SW developers design solutions using a single Flash device as the source of the BIOS, OS and/or application. This document focuses on booting Linux from a single Flash chip on the ZFx86 Integrated Development System (IDS). Apply this theory to booting other operating systems such as WindRiver’s VxWorks or other user-written special application programs. This BIOS-independent approach utilizes ZFx86 specific features built into the latest ZFx86 Phoenix BIOS. Download the latest Phoenix BIOS from the ZF Micro Devices website: http://www.zfmicro.com Using Option-ROMs ZFx86’s Flash-software booting approach relies on the option-ROM scan system, a feature found in all AT-compatible PCs. The common ISA video card BIOS is considered an option-ROM; although, it is a special case which gets executed in the very early stage of the BIOS Power On Self Test (POST) sequence. Other option-ROM examples are: ROM-BASIC used on early ATs, and all firmware on PCI or ISA extension boards (for example, network interface controllers, or SCSI controllers). During the POST sequence, the BIOS performs a so-called ROM-scan sequence: • The BIOS looks at the beginning of every 2kbyte block in the address region C8000h through F0000h to find a “55 AA” signature. • When it finds the “55 AA” signature, the next byte determines the option-ROM size in 512-byte increments. • For detecting corruption, the sum of all option-ROM bytes must equal 100h.

The Setup program lets you modify basic system configuration settings. The settings are then stored in a dedicated battery-backed memory, called CMOS RAM, that retains the information when the power is turned off. The Phoenix Technologies AwardBIOS in your computer is a customized version of an industry- standard BIOS for IBM PC AT-compatible personal computers. It supports Intel x86 and compatible processors. The BIOS provides critical low-level support for the system central processing, memory, and I/O subsystems. The Phoenix Technologies AwardBIOS has been customized by adding important, but nonstandard, features such as virus and password protection, power management, and detailed fine-tuning of the chipset controlling the system. The rest of this manual is intended to guide you through the process of configuring your system using Setup. Starting Setup The Phoenix Technologies AwardBIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it through the power-on self test (POST).
