偶然发现这个资料,上面说XPE SP2 加上2007那个升级就可以支持USB启动了,于是翻译了一下,不知有没有帮助。
Windows XP Embedded USB boot
WPE Usb启动
Enabling new scenarios for Windows XPe devices
XPe设备的新方案

Windows XP Embedded Service Pack 2 Feature Pack 2007 introduces a new Embedded Enabling Feature called USB Boot. The user can now build a Windows XPe image that boots from a USB flash drive (UFD), a.k.a., USB thumb drive, USB key, etc. The build process is straightforward using Target Designer, and preparing the UFD for boot is just as easy using ufdprep.exe (a utility included in FP 2007).
Wpe sp2 2007新版本引入了一种全新的嵌入应用功能——USB启动。用户可以创建新的镜像从USB闪存盘启动。其创建过程直接使用Target Designer(目标设计器),创建可启动U盘则只需要ufdprep.exe(2007文件包里的一个工具)
USB Boot offers many benefits. A UFD is typically removable; swapping a UFD is much easier than swapping an internal hard disk drive (HDD). An external USB HDD is somewhere between a UFD and an HDD, and FP 2007抯 USB Boot supports booting from a USB HDD as well. A UFD generally has no moving parts, which allows a UFD to be much less susceptible to mechanical failures. Recordable/rewritable CDs/DVDs have no moving parts either. However, the drives that can fully support recordable/rewritable CDs/DVDs are not widely available; the media are somewhat limited in capacity; and the whole solution is expensive. In contrast, USB ports are readily available on almost all systems; UFDs keep on increasing in capacity, as flash technologies mature; and the whole solution becomes cheaper and cheaper, positively contributing to reducing the BOM cost. Furthermore, most BIOSes on the market today support booting from a USB 2.0 device, making USB Boot a practical alternative to CompactFlash Boot.
USB启动带来了很多好处。U盘是典型的可移动设备,替换一个U盘比替换硬盘容易的多,移动硬盘是介于U盘和内置硬盘之间的一种设备,2007程序包同样支持移动硬盘启动。U盘没有运动部件,更不容易在恶劣环境下受损。Cd|dvd光盘等也没有运动部件,但是它们的驱动器却不是很普遍(嵌入式设备一般不带光驱),并且它们常常有容量限制,整体解决方案也比较昂贵。对比之下,USB接口就非常普及,U盘的容量不断增大,而且随着闪存技术的成熟其整体解决方案也更加便宜,降低了BOM的费用。而且多数市场销售的主板BIOS支持USB2.0启动方式,让U盘启动成为了CF卡启动的替代品。
USB Boot enables a flexible deployment and servicing scenario. For example, you create a golden Windows XPe image. This golden image is cloned on to 1,000 UFDs, and 500 UFDs are distributed along with new systems to various locations. When a software update is required, a new golden image is created. This new golden image is cloned on to the remaining 500 UFDs. The second 500 UFDs are distributed to swap for the first 500 UFDs, which are then returned to the central office (CO) for update. Similarly, when there抯 a software-related or UFD-related failure on a system, a working UFD is distributed to swap for the failed UFD, which is then returned to the CO for analysis and maybe re-clone.
USB启动提供了一种更灵活的部署方式和服务方案。例如,你可以创建一个完美的WPE镜像。这个版本复制到1000个U盘上,把500个随新系统分发到各地。当软件需要升级时,创建一个新的完善的镜像。把新的升级系统拷贝到剩下的500个U盘上,用新的U盘替换下旧的U盘,把旧的U盘收集回中心办公室来继续升级。同样地,如果一个U盘损坏,也可以立即用同样的U盘替换下来。
USB Boot enables a versatile diagnostic and troubleshooting scenario. For example, John, a field application engineer, is looking at a failed system. He inserts a UFD with a checked image, with debug traces on and assertions enabled, and boots from it [the UFD]. This checked image helps John determine how or why the system failed. John can also save log files on to this UFD for later in-depth analysis. The failure is UFD-related. John simply swaps the failed UFD with a working UFD containing the golden image, and then takes the failed UFD back to the CO for analysis or to re-clone an image onto the UFD.
USB启动提供了一个万用的诊断和故障分析方案。例如,John是应用领域工程师,他正在查看一个故障的系统,他把U盘插入系统来检查镜像、进行错误追踪,重新启动系统。这样就可以帮助John检查那里出了问题……
Jane, also a field application engineer, is looking at a failed HDD-based system. She inserts a UFD with a checked image and boots from it [the UFD]. The failure is a corrupted ATAPI.SYS on the HDD. Jane simply copies a valid ATAPI.SYS from the UFD to the HDD.
Jane也是一个应用领域工程师,她正在查看一个基于内置硬盘的系统,它把带有检查工具的U盘插入电脑并用U盘启动。结果检查出硬盘上的ATAPI。Sys文件损坏了。Jane秩序把一个好的文件拷贝到硬盘就行了。
To cap, Windows XPe now includes support for very exciting USB Boot scenarios. USB Boot enables deployment and servicing scenarios for which our customers have been asking and provides them with additional options for boot media on embedded devices. USB Boot considerably extends Windows XPe Embedded Enabling Feature set, offering many extra benefits and enabling more flexible and versatile usage scenarios.
总之,WPE目前开始支持力人兴奋的USB启动方式。这使分发和服务方案变得更加灵活,更能够按照客户的要求定制潜入式设备。同时也使XPE实现更过功能,提供额外的好处和更灵活的配置。
