1 00:00:12,869 --> 00:00:15,379 BIOS stands for Basic Input Output 2 00:00:15,479 --> 00:00:19,520 System. Since 2005, BIOS have begun 3 00:00:19,620 --> 00:00:23,090 to be replaced by a UEFI, which stands 4 00:00:23,190 --> 00:00:25,850 for a unified extensible firmware 5 00:00:25,950 --> 00:00:28,670 interface. Though computing experts 6 00:00:28,770 --> 00:00:30,770 and I.T. professionals generally use 7 00:00:30,870 --> 00:00:32,960 the term bios interchangeably 8 00:00:33,060 --> 00:00:36,290 when referring to both bios or you UEFI 9 00:00:36,389 --> 00:00:39,260 briefly, a bios is a text based 10 00:00:39,360 --> 00:00:41,510 interface allowing us to make 11 00:00:41,610 --> 00:00:43,430 adjustments to hardware settings 12 00:00:43,529 --> 00:00:46,730 for the computer. Whereas a UEFI has 13 00:00:46,830 --> 00:00:48,860 a graphical interface which allows 14 00:00:48,959 --> 00:00:50,870 for the use of a mouse 15 00:00:50,970 --> 00:00:53,180 in the manipulation of hardware 16 00:00:53,279 --> 00:00:55,580 settings. Bios come in many different 17 00:00:55,680 --> 00:00:57,170 designs and layouts 18 00:00:57,270 --> 00:00:59,480 which are representative 19 00:00:59,580 --> 00:01:02,000 of the manufacturer of the motherboard 20 00:01:02,099 --> 00:01:04,130 and in our case we are using this 21 00:01:04,230 --> 00:01:08,040 version of the ASUS UEFI bios utility 22 00:01:08,160 --> 00:01:09,410 and we're going to explore 23 00:01:09,510 --> 00:01:11,120 some of the basic options within 24 00:01:11,220 --> 00:01:13,790 the easy mode. Once we've explored 25 00:01:13,889 --> 00:01:15,529 some of the basic options we're also 26 00:01:15,629 --> 00:01:18,169 going to take a look at one of the basic 27 00:01:18,269 --> 00:01:20,330 settings that all computer users should 28 00:01:20,430 --> 00:01:22,130 familiarize themselves with, 29 00:01:22,230 --> 00:01:24,239 which is the boot priority order. 30 00:01:24,839 --> 00:01:28,169 More on that later. Entering the bios 31 00:01:28,269 --> 00:01:30,060 is simply a case of pressing F2 32 00:01:30,160 --> 00:01:32,330 or delete at the appropriate screen, 33 00:01:32,430 --> 00:01:33,750 there is only a brief window 34 00:01:33,849 --> 00:01:36,150 of opportunity to press the key so make 35 00:01:36,250 --> 00:01:38,370 sure that you don't miss it. Then once 36 00:01:38,470 --> 00:01:40,500 the bios is loaded, this is the bios 37 00:01:40,599 --> 00:01:42,510 that we are greeted with. The first 38 00:01:42,610 --> 00:01:44,739 thing at the top left is the system time 39 00:01:44,980 --> 00:01:47,160 and dates. In our case, this is set 40 00:01:47,260 --> 00:01:49,500 correctly. If the time wasn't set 41 00:01:49,599 --> 00:01:51,180 correctly, we would go into the advanced 42 00:01:51,279 --> 00:01:53,550 settings in order to set that. Just 43 00:01:53,650 --> 00:01:55,959 to the right of the system time we have 44 00:01:56,199 --> 00:01:58,199 some basic hardware information 45 00:01:58,300 --> 00:02:01,529 which includes our BIOS version, the CPU 46 00:02:01,629 --> 00:02:05,160 type, as well as the total memory type 47 00:02:05,260 --> 00:02:07,889 and the memory timings. Underneath 48 00:02:07,989 --> 00:02:10,110 we also have some essential system 49 00:02:10,210 --> 00:02:12,399 information related to temperature, 50 00:02:13,179 --> 00:02:14,729 CPU temperature, 51 00:02:14,830 --> 00:02:17,610 motherboard temperature, as well as CPU 52 00:02:17,710 --> 00:02:20,009 voltages. This is all critical 53 00:02:20,110 --> 00:02:22,889 information as an overheated CPU 54 00:02:22,990 --> 00:02:24,989 or motherboard can lead to problems with 55 00:02:25,089 --> 00:02:27,509 performance or worse still, damage 56 00:02:27,610 --> 00:02:29,699 to those components. Then over 57 00:02:29,800 --> 00:02:31,649 to the right of that, we have the fan 58 00:02:31,750 --> 00:02:33,539 speeds. Again, this is critical 59 00:02:33,639 --> 00:02:35,579 information. In this case, we see 60 00:02:35,679 --> 00:02:38,309 the CPU fan speed with no reading 61 00:02:38,410 --> 00:02:40,139 for the chassis fans, it might be 62 00:02:40,240 --> 00:02:42,089 necessary to troubleshoot the chassis 63 00:02:42,190 --> 00:02:44,039 fan reading, ensuring that the chassis 64 00:02:44,139 --> 00:02:46,079 fans are connected. It may be the case 65 00:02:46,179 --> 00:02:48,209 that the BIOS firmware will require 66 00:02:48,309 --> 00:02:49,769 upgrading in order to see those 67 00:02:49,869 --> 00:02:51,329 readings. Underneath that setting, 68 00:02:51,429 --> 00:02:54,220 we have some basic overclock presets 69 00:02:54,429 --> 00:02:57,399 for the CPU and it's fan. At the moment 70 00:02:57,500 --> 00:02:59,489 the setting is on normal, which will 71 00:02:59,589 --> 00:03:03,100 give a balanced ratio of CPU performance 72 00:03:03,399 --> 00:03:06,929 versus energy efficiency and quietness 73 00:03:07,029 --> 00:03:09,379 of the fan. To the left of that, 74 00:03:09,479 --> 00:03:10,909 there's the power saving option, 75 00:03:11,009 --> 00:03:14,089 which will favour energy efficiency 76 00:03:14,190 --> 00:03:16,639 and quietness of the fan at the expense 77 00:03:16,740 --> 00:03:19,039 of a small drop in performance and then 78 00:03:19,139 --> 00:03:20,720 over to the right would be the opposite, 79 00:03:20,820 --> 00:03:22,459 which is the high performance setting, 80 00:03:22,559 --> 00:03:25,440 which will favor performance of the CPU 81 00:03:25,710 --> 00:03:27,919 at the expense of energy efficiency 82 00:03:28,020 --> 00:03:29,579 and quietness of the fan. 83 00:03:29,679 --> 00:03:31,579 For our purposes will remain 84 00:03:31,679 --> 00:03:33,439 on the middle normal setting 85 00:03:33,539 --> 00:03:36,049 for a balanced ratio. More advanced 86 00:03:36,149 --> 00:03:37,759 users may wish to go into the advanced 87 00:03:37,860 --> 00:03:40,519 settings in order to customize their own 88 00:03:40,619 --> 00:03:43,519 overclocked settings, including C.P.U 89 00:03:43,619 --> 00:03:47,309 voltages, fan speeds and ram timings 90 00:03:47,490 --> 00:03:49,579 and so on. Overclocking is a very 91 00:03:49,679 --> 00:03:51,679 advanced concept, not recommended 92 00:03:51,779 --> 00:03:53,689 for the novice computer user. 93 00:03:53,789 --> 00:03:55,970 But in summary, overclocking PC 94 00:03:56,070 --> 00:03:58,309 components can provide measurable 95 00:03:58,410 --> 00:04:01,050 performance increases. But be warned, 96 00:04:01,289 --> 00:04:03,470 overclocking components will void 97 00:04:03,570 --> 00:04:06,379 manufacturer warranties. Moving on; 98 00:04:06,479 --> 00:04:08,659 at the bottom here we see the boot 99 00:04:08,759 --> 00:04:10,729 priority for all of the drives 100 00:04:10,830 --> 00:04:13,039 which are connected. In order from left 101 00:04:13,139 --> 00:04:15,049 to right will be our boot order. 102 00:04:15,149 --> 00:04:17,029 This sets which drives will be booted 103 00:04:17,130 --> 00:04:20,160 from first, second, third and so on. 104 00:04:20,760 --> 00:04:22,579 We do not have windows yet installed 105 00:04:22,679 --> 00:04:24,769 on any of these drives, so our only 106 00:04:24,869 --> 00:04:28,630 bootable drive is the Toshiba USB drive 107 00:04:28,730 --> 00:04:30,959 and then finally over to this button 108 00:04:31,059 --> 00:04:33,660 here, the boot menu, we can also see 109 00:04:33,760 --> 00:04:35,579 a list of drives which are available 110 00:04:35,679 --> 00:04:37,829 to boot from. In the next video, we look 111 00:04:37,929 --> 00:04:39,869 at the process of installing windows 112 00:04:39,970 --> 00:04:41,899 and setting up a new user account 113 00:04:42,000 --> 00:04:43,350 and for that, we are booting 114 00:04:43,450 --> 00:04:46,329 from our USB drive, which is the Toshiba 115 00:04:46,630 --> 00:04:48,279 listed here in order to begin 116 00:04:48,279 --> 00:04:50,079 the Windows installation process.
