Operating system role

The operating system is the ultimate authority in resolving hardware problems associated with the change of centuries. It is the operating system in most cases that tells applications the current time and date. The latest versions of operating systems correctly handle the change of dates from 12/31/99 to 01/01/2000. And this applies not only to operating systems that receive the date from the BIOS Continue reading

Almost everything about SPD-EEPROM …

To this day, there are still SDRAM DIMMs operating at 66 MHz frequencies that are not equipped with the SPD-EEPROM chip, which contains the most important time parameters and data on the chips used in the module and their manufacturer. The modules at 66 MHz worked flawlessly, allowing memory expansion by adding DIMM modules from other manufacturers or another type of execution. Continue reading

SDRAM PC100

Until recently, the development of new technologies for manufacturing memory components took place in parallel with the development of chipsets manufactured by Intel. But it so happened that in 1998 an advance was formed in the technology of manufacturing chipsets, and memory manufacturers lagged behind. No one could have imagined that a 100 MHz bus would powerfully clear its way. Continue reading

Z-tracks
In devices with a moving coil there are no pre-fixed positions. Instead, they use a special guidance system (positioning), which accurately brings the heads to the desired track. The system…

Golden Disks and IDE
The problem of recording "golden" discs has already been covered on our website (as well as in the journal CHIP, No. 8, 1999). However, the problems continue. Only, if earlier…
