[求助]在VM下测试U盘启动DOS不成功，U盘启动PE没问题
使用 LLM 解释/回答一下
我想用vm虚拟机测试dos启动u盘（不用pe），vm只能将U盘挂载为scsi设备启动，因此dos下缺驱动进不了系统。我已从vm安装目录下提取vmscsi.sys到U盘根目录，在config.sys中用device=vmscsi.sys加载，但是还是行不通。提示：invalid system disk, replace the disk, then press any key.
我下了个ASPIDISK.exe在config.sys中用上依然不行。
请问有知道怎么解决的朋友么？
具体所作实验如下：
用USB-ZIP模式分别做pe引导U盘和dos引导U盘，不妨称pe的为U盘1，dos的为U盘2。
实验1：U盘1在vm上启动成功；
实验2：U盘2在vm上启动失败，提示无效系统；
实验3：U盘2可以在真实电脑上启动成功。
实验1与实验2对比说明vm支持U盘以USB-ZIP模式启动，实验2与实验3对比说明真实电脑与虚拟机vm的区别在于虚拟机是把U盘识别为一个scsi设备，而在dos下正缺少scsi的驱动。
注：虚拟机是最新的VM7.0完整版
U盘大小1G，用usboot1.70做的USB-ZIP引导，在多台真实计算机中启动成功
I want to use the vm virtual machine to test a DOS boot USB drive (without PE). The vm can only mount the USB drive as a SCSI device to boot, so there is a lack of drivers under DOS and cannot enter the system. I have extracted vmscsi.sys from the vm installation directory to the root directory of the USB drive, and used device=vmscsi.sys to load it in config.sys, but it still doesn't work. The prompt is: invalid system disk, replace the disk, then press any key.
I downloaded an ASPIDISK.exe and used it in config.sys, still no good.
Is there any friend who knows how to solve it?
The specific experiment done is as follows:
Use USB-ZIP mode to make a PE boot USB drive and a DOS boot USB drive respectively. Let's call the PE one USB drive 1 and the DOS one USB drive 2.
Experiment 1: USB drive 1 starts successfully on vm;
Experiment 2: USB drive 2 fails to start on vm, prompting invalid system;
Experiment 3: USB drive 2 can start successfully on the real computer.
The comparison between Experiment 1 and Experiment 2 shows that vm supports the USB drive to start in USB-ZIP mode. The comparison between Experiment 2 and Experiment 3 shows that the difference between the real computer and the virtual machine vm is that the virtual machine recognizes the USB drive as a SCSI device, and the lack of SCSI drivers under DOS.
Note: The virtual machine is the latest full version of VM7.0
The USB drive is 1G in size, made with usboot1.70 for USB-ZIP boot, and starts successfully on multiple real computers
