There are parameters that indicate what characteristics of the chipset must be enabled and how. It usually affects to the memory RAM, to the cache memories (intern and day pupil) and sometimes to the mike, to the buses ISA, Vesa, PCI and AGP and to other devices as the ports series and parallel.

This area can be something dangerous, so I aimed at everything before changing nothing; the easiest thing is to leave more options that it could in Edict, although with that it is possible that it does not extract the yield maximum. And the fact is that to win it is necessary to suffer...

The modern basic badges (from those of the last 486) usually have the control chips of the hard disk integrated, and frequently they handle also the disk drives, the ports series and the parallel port. For it, the BIOS has diverse paragraphs to handle these devices, between them:

• Connection or disconnection of the above mentioned checkers: of special importance in case of the second channel IDE, which sometimes is disabled by defect, and which we will have to enable to connect more than two devices IDE (or the slow one and the rapid one without mixing them in the same channel, what lowers the yield).
• Ways of access to hard disks (PEEP and/or UltraDMA): the modern discs admit THAT 5 ways the PIO-0 CHIRPED, of the slowest, or do not support of this type of access (on ancient discs, of 100 MB or less), up to the most rapid, the way PIO-4. Also, recently there has appeared the way UltraDMA, even more rapid. If the checker is integrated to the motherboard, here it must specify this information. Look for them in the manual of his hard disk, in Internet on the page of the manufacturer or select Edict and do not be complicated any more.
• Directions and interruptions (IRQs) of the ports: well the ports series o are the parallel. It turns out to be very rare to need to change the values into defect, but it might be necessary to avoid conflicts with other devices that use the same values.
• Type of parallel port: the ancient standard of parallel port has remained somewhat got out of date nowadays, especially if what we want to connect is not a printer but a scanner or a unit Zip; for it, one is usually able to select other possibilities more advanced like ECP or EPP. Look in the manual of the peripheral one to know what way he must choose.
• Control of the port of infrared: although very few basic badges include the adapters and necessary cables, nowadays almost they all bring the connectors to install a port of infrared in his system. Generally it will have to enable and select his type, memory direction, IRQ and if it owes redireccionar the information of COM2 to this port.

In this menu, relatively recent (the epoch of the 486 was not implanted up to well brought in), it is where there are formed the characteristics of saving of energy of the computer.

This can be something completely superfluous, for example if we are going to use the computer of continued form to the maximum of potency, or slightly fundamentally, as it happens in portable computers or simply if we have the bad habit of lighting the computer on having come to the office and not to extinguish it until the hour of going out, so much if we are going to use it as if not.

• Power Management: literally, administration of energy. It is where it is selected if we want to enable the saving of energy and of what form; generally (disabled) Disable is offered, User defines (defined by the user) and some options predetermined for a minimal or maximum saving.
• PM Control by APM: a very important option; it determines if the energy control will have to be done according to the standard APM (Advanced Power Management, advanced administration of energy), what between other things allows Windows to be capable of suspending the team to will or, if we use a source ATX, that the system really goes out on having touched "to Extinguish the system" in the menu I Initiate.
• Video Off Method: it offers diverse options to reduce the consumption of the system of video, of which the most interesting is DPMS, although not all the monitors and graphic cards support it; read the manual of these devices to be sure, although if they are modern and of certain quality it is very probable that they incorporate it. The option Blank Screen is simply a black salvapantallas, what can be useful in TWO.

• PM Timers: to control the time that there must remain inactive the computer (System) or the hard disk (HDD) before the energy saving is activated. There exist 3 grades of saving of energy:
• Doze: it reduces the speed of the CPU (the microprocessor).
• Standby: it reduces the activity of the whole computer.
• Suspend: it limits to the minimum the activity of the computer; only type SL must be used by CPUs, as there are most of 486 rapids and Superiors.
• PM Events: a long series of events or events that must be controlled to know if the computer is inactive or working. There is habitual not to control (Disable) the activity of the IRQ8 (clock of the BIOS), since rarely it is possible to consider it as completely inactive.
• CPU Fan Off in Suspend: if the fan of the CPU is connected to the motherboard, it extinguishes it when the team is in failure, since in this moment the CPU is practically idle.
• Modem Wake Up: it activates the team when a next call is detected in the modem. He needs that the modem supports this characteristic and that it is connected to the motherboard by means of a special cable.
• LAN Wake Up: just as the previous one, but for the card of network. Also it needs to be connected to the motherboard by means of a cable.

A menu full of complicated options (on this page few ones it are not), of the class that would be desirable never not to have to alter; this is my advice, Edict chooses all the times that it could, but if it has some conflict between devices (the same IRQ, especially)... Probably wonder what has to do PNP with PCI; well, the majority of devices PCI supports PNP, in contrast to the cards ISA, much more problematic. That's why, if his badge does not have slots PCI (like the first ones for 486), there is not surprised if this menu does not appear.

Ah, for that PNP does not know it, Plug&Play, or P&P, it is a technology that facilitates the devices connection, since it is supposed that it is enough to plug and I list. Clear that not all the devices are PNP is not even a perfect technology, if it was this way this menu it would not exist...

• PNP YOU Installed: he reports to the system of if there is an operating system installed PNP, that is to say, one that he supports Plug&Play, like Windows 95 (or they say that that it does...), in whose case spends to this one the control of the devices PNP. Any way often what this pigeonhole indicates is not affected by it to the correct functioning of the system.
• Resources Controlled by: since that, resources controlled well manual, automatically well. Again, often one or another option is indifferent... whenever there is no problems, skylight.
• IRQx/DMAx assigned to: a list of the interruptions (IRQs) and channels DMA that we can assign manually, well to cards PCI/ISA PnP (compatible with PNP), well to cards Legacy ISA (cards ISA not PNP, that they are the most difficult). We will need to know the values of IRQ and/or DMA to be reserved, that will come in the papers of the problematic device.
• PCI IDE IRQ Map to: something that very probably he never needs to change, since only it affects checkers IDE not integrated to the motherboard, but in the shape of card, which it is not PNP.
• Assign IRQ to USB: since that, if the port USB must have an assigned or not interruption. If it does not have any device connected USB (and who has them nowadays?) it can liberate this IRQ for other uses; it is usually the same interruption as for one of the slots PCI or ISA.
