Advanced configuration and of the chipset
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...
- Edict Configuration: since that, automatic configuration; the salvation table when it does not become possible to do to hand. The values that it gives after the first autoconfiguration can be valid like starting point, so as always, aim at them before modifying them.
- ISA Bus Clock: the speed of the bus ISA, who theoretically must be approximately 8 MHz. Sometimes it gets like a number in MHz and other times according to the bus of the system (the PCLK), for example like 1/3 when this one is to 33 MHz, as in the 386 and 486 to 33 MHz or 486 to 66 and 100 (that go to 33 externally). The more rapid is the bus, better, but do not pass: 10 ó 12 MHz is already well, more it can be risked and it is supposed that the cards ISA are not prepared for anything over 8.
- Speed of the RAM: in this multiple ways of proceeding exist. The major let's indicate him that it is the speed of the most rapid RAM the system will go, but frequently the RAM is not so rapid or of quality as it would be desirable and the stability of the system suffers, especially on having loaded it with work. The values that indicate this speed are the cycles of access to RAM, the cycles of waiting (Clock Cycles or, sometimes, Wait States) that the rapid microprocessor grants to the slow RAM before sending him or reading of her the information.
In almost all the BIOS options exist to form automatically these values; in some BIOS it is enough to introduce the speed in nanoseconds of the memory, as well as his type (normal - FPM - EDO or SDRAM); in others it is necessary to put the number lowest in cycles. For example, a habitual blast in reading (Read) can be 7-3-3-3, and that one usually requests himself 3 as value of DRAM Read Timing or DRAM Read Wait State (or Write for writing). For EDO or rapid FPM that one 3 can be 2 and for SDRAM it is usually a 1. 7 it can be minor, enclosed 5 if we have a good chipset and rapid memory. Other times the speed of the memory is indicated simply describing it as Slowest, Slower, Faster and Fastest, of less to more rapid.
So I looked at the values for defect and go raising them (or lowering them, if there are waiting cycles) one by one, after which I began again and observed the yield and the stability of the computer. Try with Windows 9x, NT or similar, as well as with some demanding game (in the same way Quake), not with the old man TWO, who supports almost everything. As soon as I noticed instability, return to the previous value and it is already.
- Adjustments of the cache memory: similar to those of the RAM. Some of them consist of modifying the times of access, others of modifying the way of gaining access to the cache memory. Any way this depends entirely on the capacities of the cache memory itself, so it plays little with these values. For the risky or curious ones, the way Write Back is better that Write Thru (or Through), although it cannot always be used.
- Video and System Cacheable (Shadow): as it was commented in the paragraph of options of the BIOS, to copy the BIOS of the videocard or of the system of the slow ROM to the rapid RAM or, in this case, to use the cache memory for the same. It is supposed that it should increase the yield, but it can give problems with operating systems of 32 modern bits.
- Devices handling: nowadays the chipsets must handle the checkers of such devices like hard disks, ports series, etc., that are usually incorporated into the motherboard. We it will not explain for the time being, since often there exists a menu dedicated exclusive to this paragraph, named generally Integrated Peripherals.
- Configuration for software of the CPU: at present, enough basic badges have left aside the classic method to form the CPU and have chosen for solutions jumperless (literally, "without jumpers"), autodetecting the correct values of speed of bus, multiplier and voltage and/or allowing the user to select them by means of a simple menu in the BIOS.
As example we bear the program SoftMenu SoftMenu in the well-known basic badges Abit, between them the BH6, which for months has been the daydream badge for the overclockers. And the fact is that although this characteristic saves time and complications to anyone, where all his potency is seen it is when we want to see up to where we can force our mike... without passing and knowing that this supposes that it annuls his guarantee, eye.
Administration of energy
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.
Configuration of PNP and slots PCI
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.
