『楼 主』:
usb2.0 & PE?
使用 LLM 解释/回答一下
前一阵子，俺对优盘启动进行了一系列的试验与总结，并得到了相对满意的结果--用优盘和读卡器+SD卡的组合来彻底淘汰了3.5英寸软驱。
但最近发现了一个新问题---速度，毕竟，优盘也好、SD卡也罢，其数据传输速度远比不上磁盘，因此有必要有所改进。
我想，速度慢应该是两方面的原因，一是SD卡和优盘本身的物理特性决定的，对此俺们是毫无办法滴；第二则是因为驱动程序方法的原因，毕竟在DOS环境下，大部分USB设备都是工作在USB1.1状态下，因此如果能让他们工作在USB2.0状态下，想来速度是应该有所改善滴。
当然，由于我在XP环境下对硬盘、SD卡、优盘的传输速率做过较为详尽的横向测试(待全部完工后，我会把测试结果发上来)，因此这种提升到底能有多少实效，我持怀疑态度。
因此，想借这个机会，让大家集思广议，来解决下列问题---如果要在一无光盘、二不能拆机箱的前提下(有很多本本和原装机就是这个德性)通过USB接口的磁盘(包括物理磁盘和电子盘)来安装系统？
方案1、通过DOS+工作在USB1.1模式的移动硬盘 先把XP安装文件复制到目标电脑上，然后在DOS下进行安装XP系统。
方案2：与方案1类似，但使用工作在USB2.0模式下的的“高速”读卡器+高速SD卡，不过由于DOS环境下使用USB2.0设备相当困难(本坛所推荐的那些个USBASPI、UI1000DD、USBMASS、DUSE等驱动程序都试过，无一成功)，而电子盘本身的速度就低于物理磁盘，因此对本方案比较不感冒。
方案3：用网上流行的那个优盘版老毛桃PE先启动WINPE，然后在该环境下进行文件的复制或直接进行XP系统的安装。由于PE环境下硬件性能可得到充分发挥，因此我目前比较倾向于该方案。当然，目前在优盘和移动硬盘上运行PE系统也是比较麻烦的，因此还有待进行进一步的研究与分析。
很想知道各位同仁们对该问题的看法，不知你们平时碰到这样的问题是如何处理滴？
Some time ago, I conducted a series of experiments and summaries on USB flash drive booting and got relatively satisfactory results - using a combination of a USB flash drive and a card reader + SD card to completely replace the 3.5-inch floppy drive.
But recently, a new problem was discovered - speed. After all, both USB flash drives and SD cards have much slower data transfer speeds than disks, so it is necessary to make some improvements.
I think the slow speed should be due to two aspects. One is determined by the physical characteristics of the SD card and USB flash drive itself, and there is nothing we can do about it; the second is due to the driver method. After all, in the DOS environment, most USB devices work in USB 1.1 mode. Therefore, if we can make them work in USB 2.0 mode, I think the speed should be improved.
Of course, since I have done a more detailed horizontal test on the transmission rates of hard drives, SD cards, and USB flash drives in the XP environment (once all is completed, I will post the test results), so I am skeptical about how much actual effect this improvement can bring.
Therefore, I want to take this opportunity to let everyone discuss together to solve the following problem - if there is no CD and cannot open the case (many laptops and original computers are like this) to install the system through a USB disk (including physical disks and electronic disks)?
Plan 1: Use DOS + a mobile hard drive working in USB 1.1 mode to first copy the XP installation files to the target computer, and then install the XP system under DOS.
Plan 2: Similar to Plan 1, but use a "high-speed" card reader working in USB 2.0 mode + a high-speed SD card. However, it is quite difficult to use USB 2.0 devices in the DOS environment (those USBASPI, UI1000DD, USBMASS, DUSE and other driver programs recommended in this forum have all been tried and none have been successful), and the speed of the electronic disk itself is lower than that of the physical disk, so I am not very interested in this plan.
Plan 3: Use the popular USB flash drive version of Lao Maotao PE to boot WINPE first, and then copy files or directly install the XP system in this environment. Since the hardware performance can be fully utilized in the PE environment, I currently tend to this plan. Of course, it is relatively troublesome to run the PE system on USB flash drives and mobile hard drives at present, so further research and analysis are still needed.
I really want to know everyone's opinions on this problem. I wonder how you usually handle such problems?
