Solving an iron problem is very simple

The solution to the 2000 problem related to incorrect BIOS operation is based on the standard and mandatory ability of any computer to check a specific address area when booting for additional devices that have a BIOS extension specific to this device. That is why all the controllers in question include only the most necessary elements in order to change the logic of the BIOS of the motherboard, if necessary. No wonder they are so similar.

Information Disaster April 26

In April, the biggest problem of the month related to computers can rightly be considered the epidemic of the Win95.CIH virus – Chernobyl.

Everyone is used to the presence of computer viruses. Periodically they appear on the computer. Sometimes they manage to be detected on time. Sometimes something goes bad, but, as a rule, special tragedies do not occur. Last year, a new, very dangerous Win95.CIH virus was released. Continue reading

SPD EEPROM Specification

In addition to the description of the transmission interface, I2C information, the PC SDRAM Serial Presence Detect (SPD) Specification specification defines the information recorded in the EEPROM by the manufacturer. The need for such a specification was caused by the fact that the main problems when installing SDRAM in computer systems are associated with incorrect interaction between the BIOS on the motherboard and the EEPROM on the memory module.

The fact is that many Taiwanese motherboard manufacturers using the Intel 440BX chipset install their own BIOS, which has the function of disabling the reading of information from the EEPROM. In this case, the system parameters are set manually when entering SETUP, or the BIOS itself sets the system parameters for working with standard memory. Continue reading
