What is... the BIOS?
Has it already copied the current configuration of his BIOS in a few sheets of paper? And to what waiting? Anyway... under the name of Standard CMOS Setup or similar, it usually include the putting on the day of the date and hour of the system, as well as the configuration of hard disks and disk drives. The handling screen is usually similar to this one:
To change the date and hour does not have any more history than to place on her and to introduce the piece of news, good by means of the keyboard, the mouse, the cursors or the keys of advance and regression of page. Practise a little with it, this way it will be prepared for when it is going to change something more critical.
The type of disk drive and screen is also simple to understand and to handle. Except prehistoric cases the screen will be VGA or EGA, and the above mentioned it is already quite strange; when he says "monochrome" it usually refers to screens MGA, those of white, green phosphorus or amber of more than ten years ago, not to the VGA of scale of gray modern, bear it in mind.
The most interesting and difficult thing is in the configuration of the hard disks. In general they will be only neither discs of the type IDE (including the EIDE, Ata-4, Ultra-DMA and other enlargement of the standard), in no case SCSI (go, almost a couplet, SCSI says to himself "it is - ca-si") nor ancient others like MFM or ESDI, which are formed of other forms, for example by means of another BIOS of the proper checker SCSI.
In the ancient cases (many 486 and previous) we will be able to give values only to two hard disks, which the first one and Slave form like Teacher, master's degree, slave, the second one, of the only channel available IDE. In the most modern cases of checkers EIDE we will be able to form up to four, in two channels IDE, each one with his teacher and his slave. For those who do not understand anything of this, I recommend the reading of the paragraph to Install a hard disk.
The fields to be refilled are usually:
For example, in the image a 420 MB disc appears, with 986 cylinders, 16 heads... and being employed at Normal way, since it does not overcome 528 MB. All these values usually come in a sticker adhered to the hard disk, or can be by means of the utility of autodetection of hard disks, which learns further on.
In any case, generally there exists more than one possible combination of values. Certainly, the readership of CD - ROM of type IDE is not formed usually in the BIOS; this way, although really they occupy one of the places (the teacher of the second channel or the slave of the first one) usually owes to allow the above mentioned pigeonholes in target, electing None or Edict as a type.
Options of the BIOS
Or generally, in English, BIOS Features. It is a question of the diverse possibilities that the BIOS offers to realize certain tasks of one or another form, in addition to enabling (enable) or disabling (disable) some characteristics. The most important are:
