On the downside, however, increased resolution also decreases the size of standard text and icons on the screen. Note that once you have chosen a resolution, it cannot be changed. A laptop's video circuitry can simulate a change in resolution, but the resulting image will be much less sharp than the image at the screen's original or native resolution.
In the distant past, some laptops, such as the IBM PC Convertible and the Toshiba T, used wider display screens because that was all that was available. When LCD screens came out, the public quickly gravitated toward this standard shape. Now, however, with the popularity of DVDs and high-definition TV, many manufacturers are installing widescreen displays on their systems see Figure 2.
These displays have a wider aspect ratio of Widescreen laptops are usually sold as multimedia or desktop replacement systems, due to their larger and clumsier to carry sizes.
As more people use their laptops in home entertainment systems or as personal DVD players, expect this number to grow. Photo courtesy of Dell Inc. For example, many so-called "widescreen" laptops have Personally, I would rather have a standard aspect ratio At the higher x pixel resolution, you'll actually be able to fit more open windows web pages, applications, and so on both in width and depth than you could on a WXGA screen.
The primary advantage of using a widescreen on a laptop is that human vision sees more peripherally than vertically, making wider screens better suited to what you actually see on them.
Video Accelerators A crucial and sometimes overlooked aspect of computer performance is the speed of its video accelerator. This chip, shown in Figure 2. Computer game players have been especially sensitive to the speed of their video processors because this can greatly influence the quality of their entertainment. But business users should also be aware that a video accelerator can impact tasks such as sales presentations. Note that as in the case of processors, laptop video accelerators are usually not quite as fast as those in desktop models.
Typical video accelerators are listed in Table 2. The amount of video memory used for laptop graphics chipsets currently varies from 64MB to MB. In most cases the video memory is dedicated memory separate from main RAM used to hold information that will eventually be displayed on the screen. However, systems with video accelerators built into the motherboard chipset such as the Intel Media Accelerator use shared memory, which means that the video accelerator borrows main system RAM for video use.
Since there is no dedicated video RAM, this results in a less expensive design which also uses less power , but sacrifices performance when compared to dedicated video memory designs. The more video memory available, the more colors the laptop can display and the faster the video accelerator can operate.
Large amounts of video memory are also useful for 3D graphics such as in games. Purchasers should be careful to note the type of video chipset and amount of video memory in a potential new notebook. Although there are a few select models with upgradeable graphics, in most cases the video accelerator components cannot be changed. You'll find more detail about mobile video chipsets in Chapter Spindles Storage The classic three-spindle laptop is disappearing.
These systems generally had three forms of rotating memory: a hard drive, an optical drive, and a floppy drive. Now, because floppy disks are so rarely used, many laptop manufacturers have been leaving them off in order to save weight and lower costs. In some two-spindle systems, the floppy can be swapped into the storage bay normally occupied by the optical drive, but you can't run both simultaneously.
In most cases, the floppy is relegated to being used as an external device that connects to the system via a USB cable. Since floppy drives aren't used much anymore, this doesn't seem to bother many people, which is one reason the three-spindle designs are fading. As average file sizes continue to grow well past the capacity of a floppy, this once familiar component may well disappear altogether. The most important drive in a laptop is its hard drive. Currently, drive sizes range from 20 to GB.
Many experts suggest that users get as much hard drive storage space as they can afford. When users eventually purchase a digital camera or start storing audio and video on their hard drives, they will soon take advantage of all the storage space they have available. External USB drives can also be used to extend the storage of a laptop, and are actually quite excellent for backup, but when mobile, you generally have to rely on the drive that is installed internally in the system.
Some laptops have drives that rotate at higher speeds than other drives. The use of faster rotating drives will positively impact system performance by a significant amount. A faster-spinning drive enables the system to access information from the hard drive more quickly. Faster drives also have a major impact on startup boot times, as well as the time it takes to hibernate and resume from hibernation. For some time there has been a variety of optical drives available for laptops. In most cases these drives are not nearly as fast as their desktop counterparts, especially where DVD burning is concerned.
Chapters 9, "Hard Disk Storage," and 10, "Removable Storage," discuss storage options in more detail. Expansion Options Laptop components are so tightly crammed together that few expansion options are available. These cards, also known as PC Cards or CardBus Cards, were originally designed as memory cards but are now capable of providing a wealth of features. In addition to the older bit PC Card, there is also a high-speed bit CardBus Card that is required for high-speed wireless networking cards.
The fact that drivers for MS-DOS are not available for newer technology is not particularly surprising. Can you help me put the right stuff in autoexec. Thank you very much in advance.
Joined Jul 1, Messages 18, Go to this link and download the pcdrd. On the View tab, deselect "Hide the extension for known files". Doing this will allow you to see the entire file label. Once done, turn this feature back ON. Now you can start the computer with this diskette and select Command prompt with CD Support.
I can't thank you enough for responding to my posting. Unfortunately for me , your procedure didn't work. Hopefully, I read your very explicit and detailed description correctly and performed the steps as you indicated: I created a boot floppy from within Windows I renamed autoexec.
Although use of the new boot floppy resulted in the CD-ROM actually being accessed or otherwise powered-up for a brief moment, the bootup went along for a while then displayed that no CD-ROM could be found. This is much, much more than it has ever done with any and all of the other attempts I've made to boot up with CD-ROM support. It does now buy still does not recognize that a CD drive is attached. I'm a bit confused with one sentence you included in your original posting: "Now you can start the computer with this diskette and select Command prompt with CD Support.
Did you mean something else??? Any additional assistance would be greatly appreciated. I extracted: Arccd. I did nothing else with pcdrd. The download pcdrd. Since the Startup diskette is "Universal", maybe you should prepare a startup diskette specifically for your computer and avoid loading files for which you have no use.
All you have to do is to copy all files extracted from the pcdrd. The computer will boot directly to a command prompt. It will give you access to the high memory area block.
If that does not work, enter the BIOS setup and set the values to default. However, I suspect it is an OEM of some other mfg. The card has a dip switch for bit or CardBus mode. I can run under Win2K using either mode. Regards, Carnegie.
However, I suspect it is an OEM of - some other mfg. The card has a dip switch for bit - or CardBus mode. I can run under Win2K using either - mode. Set it to not mode. No, I don't own my i any longer. I sold it. Perhap you can get it work with them? These devices are also not supported in DOS. Although these devices might work in DOS or with Ghost, Ghost has not been written for compatibility with these devices.
If Ghost does work with one of these devices, there is no assurance that it will work consistently; that is, it will one time and not work another time.
