This address is the address of the first instruction within the. Its the responsibility of the mainboard. The system. bios is the very first program that the processor executes. Below is an. explanation of the typical memory map of an x. Address Range. Detailed Explanation. Compatibility area00. FFFFFhDOS Area 0. FFFFhThe DOS area is 6. KB in size and is always mapped to the main memory RAM by mainboard chipset. Legacy VGA Ranges andor Compatible SMRAM Address Range A0. BFFFFhThe legacy 1. KB VGA memory range A0. BFFFFh Frame Buffer can be mapped to AGP or PCI. Device. However, when compatible SMM space is enabled, SMM mode processor accesses to this range. Non SMM mode processor accesses to this range. Expansion ROM Area C0. DFFFFhThis is the 1. KB ISAPCI Expansion ROM region. The system BIOS copies PCI expansion ROM to this area in RAM. PCI expansion card ROM chip and execute it from there. As for ISA expansion ROM, it only exist. ISA expansion card and sometimes the expansion ROM chip of the corresponding card is hardwired. In most case, part of this memory range can be assigned one of four readwrite. This state assigment is controlled by the setting of certain. The system BIOS is responsible for assigning the correct readwrite state. Extended System BIOS Area E0. EFFFFhThis 6. 4 KB area is divided into four, 1. KB segments. Each segment can be assigned independent. BIOS ROM chip via the system chipset. Typically, this area is used for RAM or ROM. On systems that only supports 6. KB BIOS ROM chip capacity, this memory. RAM. System BIOS Area F0. FFFFFhThis area is a single, 6. KB segment. This segment can be assigned read and write attributes. It is. by default after reset readwrite disabled and cycles are forwarded to BIOS ROM chip via the system chipset. By. manipulating the readwrite attributes, the system chipset can shadow BIOS into the main memory. When. disabled, this range is not remapped to main memory by the chipset. Extended Memory Area1. FFFFFFFFhMain system memory from 1 MB 1. Top of of RAMThis area can have a hole i. RAM but mapped to ISA devices. This hole is dependent on the. AGP or PCI memory space from the Top of RAM to 4 GB FFFFFFFFhThis area has 2 specific ranges. APIC Configuration Space from FEC00. GB 2. 0 MB to FECFFFFFh and. FEE00. 00. 0h to FEEFFFFFh. This is also dependent on the mainboard chipset. Some chipset. doesnt support APIC, hence this mapping doesnt exist. High BIOS area from 4 GB to 4 GB 2 MB. This address range mapped into the BIOS ROM chip. But its dependent on the mainboard chipset. Some chipset only support mapping 4 GB 4. GB 2. 56. KB. for BIOS ROM chip. However, the 4 GB 4. GB 6. 4KB memory area is the least common denominator for all. BIOS ROM chip. In most case, anything outside of these specific ranges but within the PCI memory space top of RAM 4. GB is mapped to. PCIAGP device that needs to map their local memory memory local to the PCI card to system memory space. This mapping is normally initialized by system BIOS. Access to this memory space is routed by the system chipset. In the case of AMD Athlon. Opteron platform, this routing is handled by the processor. In the memory map above, of particular interest is the expansion ROM. We will be dealing with this area later as we are developing the. PCI expansion ROM. In this section, we are not going to provide a complete explanation. Pn. P BIOS architecture. We will only explain parts of the Pn. P. BIOS architecture that are needed to develop our hardware software. A more thorough explanation regarding the system BIOS can be. Award BIOS Reverse Engineering Paper 3. The parts of Pn. P BIOS that are important to our project are the. ROM, i. e. initialization code that. BIOS to operating system after the BIOS has. Initialization of option ROM is part of. POST Power On Self Test routine in the system BIOS. The related. informations from the Pn. P BIOS Specification 1. A 5 are provided below. The following steps outline a typical flow of a Plug and Play system BIOS POST. All of the standard ISA. Plug and Play POST enhancements. Step 1. Disable all configurable devices. Any configurable devices known to the system BIOS should be disabled early in the POST. Step 2. Identify all Plug and Play ISA devices. Assign Card Select Numbers CSNs to Plug and Play ISA devices but keep devices disabled. Also determine which. Step 3. Construct an initial resource map of allocated resources. Construct a resource map of resources that are statically allocated to devices in the system. If the. system software has explicitly specified the system resources assigned to ISA devices in the. Set Statically Allocated Resource Information function, the system BIOS. If the BIOS implementation provides support for saving the last working configuration and the. This information will also be used to. Step 4. Enable Input and Output Devices. Ham Radio Deluxe Key'>Ham Radio Deluxe Key. Select and enable the Input and Output Device. Compatibility devices in the system that are not. For example, a standard VGA adapter would become the. If configurable Input and Output Devices exists, then enable these devices. If Plug and Play Input and Output Devices are being selected, then initialize the. ROM, if it exists, using the Plug and Play option ROM initialization procedure. Step 5. Perform ISA ROM scan. The ISA ROM scan should be performed from C0. EFFFFh on every 2. K boundary. Plug. Zara Studio 2.2. Play Option ROMs are disabled at this time except input and output boot devices and will. ROM scan. Step 6. Configure the Initial Program LoadIPL device. If a Plug and Play device has been selected as the IPL device, then use the Plug and Play Option.
