Computer hardware abbreviation: CPU：Central Processing Unit, also known as central processing unit or microprocessor.
ram: random access memory, which is commonly referred to as "memory".
rom: read-only memory, read-only memory.
edo: extended data output, expanding data output. With the increasing processing speed of CPU, the data transmission speed of DRAM is correspondingly required to be increased. Generally speaking, the data transmission speed of FPM(Fast Page Model)DRAM is 6-7 ns, while that of EDO DRAM is three times faster than FPM, reaching 2ns. At present, SDRAM(Synchronous DRAM) is the fastest, and its access speed is as high as 1ns.
SDRAM: synchronous dynamic random access memory, also called synchronous DRAM, is a new generation of dynamic memory. It can use the same clock as the CPU bus, so SDRAM memory can greatly improve the performance of the computer compared with EDO memory.
Cache: English means "cellar (where explorers and others store grain and equipment, etc.); The artifact office. " The computer is a cache memory, which is located between the CPU and the main memory DRAM(Dynamic Randon Access Memory), and is a small but high-speed memory, usually composed of SRAM(Static Random Access Memory).
CMOS: the abbreviation of complementary metal oxide semiconductor, which means complementary metal oxide semiconductor (referring to complementary metal oxide semiconductor memory). CMOS is a battery-powered memory (RAM) used in most computers at present. It is an important tool to determine the hardware configuration of the system, optimize the overall performance of the microcomputer and maintain the system. It saves some information about the system hardware settings, which will continue to exist after shutdown (this is completely different from RAM). When the computer is turned on, it needs this information to start the system. If the information retained in CMOS is confused by carelessness or accident, the computer system will not start normally.
PCI: peripheral component interconnection, local bus (bus is a high-speed channel used by computers to transmit information from one device to another). PCI bus is an advanced bus structure at present, and its function is greatly improved compared with other buses. It can support burst read and write operations, and the highest transmission rate can reach 132Mbps. It is one of the fastest buses for data transmission and can support multiple groups of peripheral devices at the same time. PCI is not restricted by CPU processor, and can be compatible with all kinds of existing buses. Its motherboard slot is small, so its cost is low and it is beneficial to popularization.
Seagate: American Seagate hard disk manufacturer. Seagate means "the gateway to the ocean" in English, and often refers to the canal leading to the sea.
quantity: English means "quantity, total quantity". Famous hard disk trademark, Quantum Corporation.
Maxtor: "crystal", American Maxtor hard disk company.
LD: laser disk, also known as laser video disk.
CD: compact disc, compact disc, also called compact disc.
CD-rom: compact disc-read only memory, compact disc-read only memory (storage), also called "read only disc".
vcd: video compact disc, video compact disc, which is commonly referred to as "compact disc".
DVD: Up to now, many people regard DVD as the abbreviation of Digital Video Disc. In fact, since Sony/Philips and Toshiba/time warner Inc. two DVD development groups reached a unified standard for DVD in September 1995, the connotation of DVD has changed greatly, and it has become the English abbreviation of Digital Versatile Disc. Versatile "universal" indicates the diversification of DVD uses, which can be used not only for film and television entertainment, but also for multimedia computers and other fields. At present, it can be divided into five types according to its use: 1. CD-ROM for computers; 2. Home audio-visual CD-DVD-Movie; 3. DVD Audio； for music appreciation; 4. A write-once CD-ROM-DVD-R; 5. DVD-RAM, a CD that can be read and written many times.
Modem: Modem is an essential tool for Internet on home computers. The word modem is not found in general English-Chinese dictionaries. It is an abbreviation of MOdulator and DEModulator. Modem is an indispensable external device to realize computer communication. Because the data of a computer is a digital signal, it is necessary to convert the digital signal into an analog signal (modulation signal) suitable for transmission in order to transmit it to another computer or other terminal (such as teletypewriter) at a long distance through transmission lines (such as telephone lines). At the receiving end, it is necessary to restore the received analog signal to the original digital signal, which requires the use of modems.
UPS: short for Uninterruptible Power Supply. It appeared with the birth of computer, and it is one of the important peripheral devices of computer. UPS is a constant-voltage and constant-frequency uninterrupted power supply with energy storage device and inverter as the main component, which is used to protect the computer from losing important data when power is suddenly cut off.
TFT: active matrix color display, referred to as TFT display, is specially used for notebook computers. TFT display has the advantages of fast refresh speed, vivid color and bright brightness. In addition, it also has the necessary characteristics of "green computer" such as no flicker, no radiation and no static electricity.

level of hardware check during p>Boot POST: set to "MIN. IMAL "(the default setting), the POST will only be checked if the BIOS is upgraded, the memory module is changed
or the previous POST is not completed. Set to "THOROUGH" to perform a full set of hardware check during POST.
Config Warnings setting: this option is used to set whether to alarm when the system uses a low-voltage power adapter or other unsupported configurations. Set
to "DISABLED" to disable the alarm, and set "ENABLED" to enable the alarm.
Internal Modem built-in Modem: use this option to enable or disable the built-in modem. When disabled, the Modem is not visible in the operating system.
LAN Controller network controller: use this option to enable or disable the PCI Ethernet controller. When disabled, the device is not visible in the operating system.
pxebis policy/pxebis default policy
pxebis policy: this option controls how the system handles (Boot Integrity Services(BIS)) authorization requests when there is no authentication. The system can
