我用过很多U盘做启动盘，但发现大多容量比较大的（512M以上）不容易做成启动盘，不仅是有的制作工具有容量限制。我在一次用威刚的512M运动碟做启动盘，用FlashBootWizard里制作一个带最小DOS的启动盘时，使用DOS映像制作，始终都成不了，但用自带的FREEDOS却可以，我觉得很奇怪，之后就用“复制启动型的USB磁盘”（该方法用在清华紫光1G盘上可行），但还是不行，没有办法，于是在威刚官方网上找到了制作工具，这个制作工具有一个要求就是要一个WIN98系统，因此我找了一个98系统制作后成功进入DOS，之后我将我以前用的U盘系统拷入该U盘，但发现根目录下的io.sys的容量不同，拷贝完毕重启机器，从U盘又启动不了，我在想很有可能是那个io.sys的原因，在网上找到了另一个200多K的io.sys，复制回U盘后，果然可以启动。不知道大家的U盘也是不是这个原因。现在网上流行的DOS系统用的很多很多是被修改过的io.sys，也就是去掉了启动时的win98画面，也可以启动win32迷你版的那个。如果朋友们在制作不了U盘的DOS启动盘时，用我的方法看行不行，这个io.sys我放在这里
http://hi.cech.com.cn/download/file_share_3650181.html给大家共享。当然，用了这个io.sys，就启动不了win32的迷你版，大家看着办吧。另外，不管是用修改的还是未修改的io.sys，在一些U盘上启动linux系统都存在问题，可是小容量的（256M及以下）U盘却可以。因此我现在正在做的带有LINUX的超级U盘系统一直发布不了(所带的这些LINUX：FANX与GEEXBOX单独用小容量的U盘可以正常使用)。

I have used many USB flash drives to make bootable disks, but I found that most of the ones with larger capacities (above 512M) are not easy to make into bootable disks. It's not only because some making tools have capacity limitations. Once I tried to make a bootable disk with a 512M ADATA Sport Drive using FlashBootWizard to make a bootable disk with minimal DOS. When using DOS image making, it never succeeded, but it could work with the built-in FREEDOS. I found it very strange. Then I used the "Copy bootable USB disk" method (this method worked on a 1G Tsinghua Unisplendour USB flash drive), but it still didn't work. There was no way, so I found the making tool on the ADATA official website. This making tool has a requirement that a WIN98 system is needed. So I found a 98 system, made it, and then successfully entered DOS. After that, I copied my previous USB disk system into this USB flash drive, but I found that the capacity of io.sys in the root directory was different. After copying and restarting the machine, it couldn't boot from the USB flash drive. I thought it was very likely due to that io.sys. I found another io.sys of more than 200K on the Internet, copied it back to the USB flash drive, and果然 it could boot. I don't know if your USB flash drives also have this problem. Now many of the popular DOS systems on the Internet use a modified io.sys, that is, removing the win98 screen during startup, and it can also boot the win32 mini version. If friends can't make a DOS bootable disk for a USB flash drive, see if my method works. I put this io.sys here
http://hi.cech.com.cn/download/file_share_3650181.html for everyone to share. Of course, with this io.sys, the win32 mini version can't be booted, so you can decide. In addition, whether using a modified or unmodified io.sys, there are problems booting the linux system on some USB flash drives, but the small-capacity ones (256M and below) USB flash drives can. Therefore, the super USB disk system with LINUX that I am currently making has been unable to be released all the time (these LINUX: FANX and GEEXBOX can be used normally with small-capacity USB flash drives alone).
