In addition to resources of support of UltraDMA/66 protocols, UltraDMA/100 designers of motherboards quite often apply the specialised chips providing functions of hardware monitoring, being mandatory attribute of the architecture of modern high-powered and highly reliable systems.


The circuit of monitoring of hardware of the computer

Unfortunately, the chip set architecture i440BX AGPset does not provide support of hardware monitoring, for example, how it is carried out in series matching components i8xx from Intel, chip sets VIA etc. However this possibility can be realised by means of special chips, such as, for example, LM78, LM79, Winbond W83782D. One of examples of usage of chip Winbond W83782D with the specified purpose in the motherboard architecture which basis is the chip set i440BX, is presented in an appropriate figure.

It is necessary to mark, that some manufacturers of the motherboards releasing the products on modern chip sets which structure includes resources of hardware monitoring, are not satisfied by their possibilities and use either the specified chips, or similar. So, for example, ASUSTeK corporation which is one of the largest manufacturers of motherboards, rather often applies a monitoring chip own developments. As an example it is possible to result PC Health Monitoring, realised by means of firm chip ASIC (Aplication Specific Integrated Circuit) AS99127F. Quite often similarly this corporation arrives for implementation of network functions and of some additional controllers, for example, IEEE1394.

Inclusion of chips of hardware monitoring and input/conclusion in the architecture of the computer with a chip set i440BX AGPset

And as to the systems, which basis is the discussed specialised set of system logic, the chips similar Winbond W83782D and High Point HPT 366 (or High Point HPT 370), are not a part of a package of chips of a chip set i440BX AGPset. However, as additional components, these, and also some other units, allow to add functionality of the given legendary chip set and to prolong the period of its expedient usage as a basis as a part of high-powered motherboards. Release of similar cards proceeds, despite release abbreviation i440BX, linked to appearance of new chip sets with the improved architecture, Intels developed and released by corporations, VIA, ALi and SiS. The given chip sets differ more difficult construction and wider set of functionality on matching i440BX.

However it is necessary to mark, that testing of the motherboards created on the basis of a chip set i440BX, shows, as a rule, their advantage on such important metric, as productivity. Despite release of the new products developed on the basis of more perfect sets, for example, such as i815, motherboards Abit BE6-II and ASUS P3BF on a basis i440BX till now are the original measurement standard of efficient and steady cards. By the way, the considerable mite in their popularity is brought also by such fact, as lower price in comparison with the newest variants of motherboards on the basis of new specialised sets.

It is necessary to mark, that by Intel corporation it is made more than 100 million chip sets i440BX. By 2000 this chip set became the most popular and mass chip set for all previous computer history. And, nevertheless, despite the popularity and the successful architecture, and also on efforts of manufacturers of the motherboards entering into their architecture all new and new units for the purpose of the extension of functionality (for example, RAID) the products, the chip set i440BX all the same should give way sooner or later to new, more perfect sets. However will transit yet not enough time while the products created on the basis of the newest specialised sets of the system logic, will really supersede the predecessors which basis is the remarkable chip set i440BX AGPset, influenced development of all computer branch.
