At present, most notebooks have removed the "old" settings such as floppy drive (including many desktops), while some ultra-thin notebooks have also removed the optical drive in order to reduce the size. Naturally, for these notebooks, portability is achieved, but once the machine breaks down, it is necessary.
Reinstall the system and there is no external drive available at hand. What should I do?
Generally speaking, there are several ways to reinstall the operating system without disassembling the ultra-thin flat floppy drive notebook hard disk:
1, if the notebook supports USB boot (some old models only support USB floppy drive boot. However, although some models support USB CD-ROM drive startup, you can't start it with the general CD-ROM drive external box, because starting from USB CD-ROM drive requires the circuit support in the external box, and it must be compatible with the notebook, and you can only know it by trial), so the simplest method is to take a dual boot U disk and format it into a USB boot floppy disk through the formatting tool of U disk and insert it into the USB interface of the notebook to start it, without buying a USB floppy drive. In addition, if you have a USB mobile hard disk box, you may be able to use it. Of course, whether it can be used is also related to whether the interface circuit in the hard disk box is compatible with the USB boot of the notebook. Sometimes, even if the hard disk box can really support startup (OK on other computers), there is still a problem that it is not compatible with a specific notebook computer, and we need to experiment to know.
It should be pointed out that it is no problem to format the notebook hard disk partition after booting with USB floppy drive. The difficulty lies in how to get the installation files of the operating system to the hard disk. Generally speaking, you can find the USB drive by loading the DOS boot disk driven by USB storage device to boot the system (there are many details about how to make DOS support USB storage devices in the forum of the new DOS era, and download the image file of the super boot floppy disk). However, I suggest that you copy the installation file to the hard disk first, and then use SYS C: to enable the hard disk to boot, and then boot the operating system from the hard disk. This proposal mainly takes into account the hidden compatibility problems caused by running the installation program through USB CD-ROM in DOS.
I have encountered the following problems. The ultra-thin, plain floppy notebook I bought for others supports USB floppy boot, but I don't know if my CD-ROM drive box doesn't support boot function or the notebook itself only supports USB floppy boot and doesn't support USB CD-ROM drive boot. Anyway, I can't successfully boot from the CD-ROM drive. So I thought of using the super boot floppy disk supporting USB storage devices to boot from the USB floppy drive, and then copying the installation files on the CD to the hard disk to install the operating system after finding the U disk. Unfortunately, I found that the USB floppy drive can boot successfully without connecting the USB drive box, but once the USB drive box is connected and booted at the same time, the two USB devices obviously seem to be "fighting" in the middle of the boot process. In a word, USB optical drive and USB floppy drive can't be used at the same time under DOS on this notebook.
In contrast, the same USB external drive can always be found and used normally after booting the internal floppy drive of the desktop with the same boot floppy disk. In desperation, we have to start the USB floppy disk instead of the U disk, then make the hard disk into a startup disk to drive the U disk, and then copy the installation file to install the Windows system.
In addition, the outer box of the CD-ROM drive I use is Changshou 088 Forever model, with USB 1. 1 interface. After testing, it is used on a desktop computer that supports USB CD-ROM drive startup, and it is impossible to start the computer from its CD-ROM, nor on that notebook computer.
In addition, I can't use USB optical floppy drive at the same time under DOS, which should not be due to the insufficient power supply of USB interface (or the total power of notebook). Because, under the original Windows 98 ME of this machine, it is obvious that USB CD-ROM floppy drive and floppy drive can be used simultaneously.
Therefore, that experience reminds us that there is still a compatibility problem between hardware and software.
2. You can also consider booting from PC card CD-ROM. For ultra-thin models that do not support USB startup, this may be the last resort to install the system without disassembling the hard disk. However, the PC card discs that support the boot function are often original goods (bootable PCMCIA discs, the word "bootable" is too important). The refurbished PCMCIA optical drives sold in the second-hand market are all made by JS manufacturers taking apart the optical drives and adding a simple interface circuit and shell made by JS. This circuit is "simple" or JS doesn't understand the principle at all, which leads to that these PCMCIA optical drives with the price of1/kloc-0 ~ `140 yuan almost don't support the boot function. So before you buy, be sure to support the CD-ROM drive as much as possible.
The second-hand notebook market is a hodgepodge. You can find almost all the rare things you didn't expect, such as the base, as long as you can afford it. However, from the economic point of view, it is best to find a floppy drive that matches your notebook and connect it through the expansion port (even the CD-ROM drive is much more expensive, not to mention some notebooks do not support CD-ROM drive startup). Found it and solved the boot problem. The old external floppy drive is generally around 40-60 yuan.
Finally, by the way, only optical soft interchangeable notebooks with optical drive should generally support CD boot. If such a notebook doesn't support CD-ROM startup, you can only find a friend or a compatible replaceable floppy drive in the second-hand market. The treatment method is described in paragraph 1. First, the hard disk is considered bootable by floppy drive (remember to add the CD-ROM drive to CONFIG. SYS and AUTOEXEC. BAT), and then you can replace it with an optical drive and install it directly from the optical drive or copy it to the hard disk.
A friend who just left his job wants to help people develop a single chip microcomputer application. More than a month ago, I bought him an ultra-thin second-hand notebook with no built-in soft light, Panasonic CF-S5 1 (classic appearance, but low configuration, no built-in serial port and external VGA port.
, configure C2-400/11.3 "TFT XGA/192m/USB, and the Japanese BIOS settings in it should not support USB startup). Win2000 Pro/mini-Win98 dual system was available when I bought it. Considering the need to reinstall the operating system in the future, I also persuaded my friend to buy another external expansion port floppy drive (although the floppy drive can be directly connected to the notebook, we are lucky to find the port expander of this notebook with VGA/COM/LPT/FDD interface), including the cost of upgrading the extra 128M memory module, a full set of external expansion ports/floppy drives and replacing the battery. Hehe, it only cost 2000 yuan.
About 10 days ago, because my friend opened the width, I didn't expect to get a virus back from the Internet. He was too lazy to use the dual operating system he brought back, so he asked me to help reinstall Win2000 Pro.
Fortunately, I have to let him buy a floppy drive! Booting the notebook is no longer a problem, and the key to the remaining work is how to put the huge Win2000 Pro installation files on the hard disk.
I use the DOS7. 10 super boot floppy disk mentioned in the first post, and boot from the external expansion port floppy drive of the notebook. After trying different startup CONFIGuration options, the notebook can only detect USB external drives and read CD files after starting from the third option (just use it, too lazy to study config. SYS)。 So partition/format the hard disk and quickly copy the Win2000 Pro installation file on the CD to a folder on the D disk of the hard disk.
Next, make drive C bootable through SYS C:, then boot from drive C, and then run the DOS installer of Win2000 Pro in drive D:.
Win2000 Pro has been successfully installed.
In the process of copying installation files and executing installation, we should pay attention to the following points:
1. If you encounter difficulties when mounting USB-CDROM, for example, no matter which startup project you choose, you can't find the CD or read and write normally. You can also study the configuration. SYS and AUTOEXEC. DOS7. 10 Super Boot the BAT file in the floppy disk, adjust the control parameters of some drivers, the order of device statements, or change other standby USB devices in the boot disk.
2. It is particularly interesting that in some cases, the reason why the external USB optical drive can't be detected is not just the above mentioned. The original clever thing is that we must seize the right opportunity to restart the power supply of the USB external box at the moment when the USB storage device driver is loaded (it is ok to unplug the USB connector when powered on)! Without this experience, if the external box is always open and the USB port is connected, there may still be cases where the external USB storage device can't be found or can't be read and written if it is found!
At this point, some good device drivers will prompt you to plug in USB devices, but the prompt information is always late, and your opportunity to take action is fleeting and difficult to grasp. And some unfriendly USB device drivers may just have no prompt information to display. Therefore, I always close and open the USB external box when the last program loading action is close to completion, so as to ensure the successful loading of USB storage devices.
3. Before copying the installation file to the hard disk, you must load a disk read-write buffer program, such as SmartDrv.exe, during the boot process of DOS7. 10 super boot floppy disk; Otherwise, the process of copying installation files will be very long.
4. After copying the files needed to install the system to the hard disk, there is no need to load SmartDrv.exe and other disk read-write buffers when installing the operating system. Remember, it is best not to let the configuration. SYS and AUTOEXEC. The BAT file of disk C is reloaded into the disk read-write buffer when the hard disk is started, so as to avoid compatibility problems affecting the installation of the operating system (I had such experience a long time ago, but it is best not to load SmartDrv when installing the operating system, otherwise even if it seems that the operating system is successfully installed, there will still be inexplicable problems in use). In the above example, I only installed the system from disk D when there was no configuration file. SYS and AUTOEXEC. BAT is in the root directory of drive C, so no problems were found in later use.
