这个是我从其他论坛转来的一个问题，因为涉及到dos下光驱驱动及dos启动盘的问题，所以冒昧的贴到这里，希望dos联盟的高手能帮助我，谢谢了

【问题一：已解决】
【1】用易驱带普通的CDROM光驱来启动机器，用windows98光盘，能启动机器到dos，但不能读取光驱内windows98光盘的内容。屏幕显示：
Device drivers not found: "OEMCD001"
No valid CDROM device drivers selected
the windows98 setup files were not found
A:\>
dir A盘的内容，都是一些.sys .exe类文件。可以确定的是A盘肯定不是光盘，因为windows98启动光盘中的内容不是这样的；也不是硬盘，因为硬盘是NTFS格式的，无法在DOS中被读取。
【2】用usb外置光驱（仿制的IBM DVDROM）读windows98光盘来启动机器，也能启动机器到dos，但同样不能读取光驱中的内容。屏幕显示同上。
【3】机器连上USB外置光驱，再连上朗科FDD启动U盘，并用后者FDD启动机器，能启动机器到dos，但同样不能读取光驱中的内容。于是在dos中打入如下命令，试图在dos环境中装载光驱驱动：
打入device.com vide-cdd.sys
屏幕显示：
IDE/ATAPI CD-ROM Device Drives Version 2.14 10:48:22 02/17/98
Error: No CD-ROM drivers detected at all
Error: Device driver aborts loading
打入shsucdx.exe
屏幕显示：
SHSUCDX can't intall
Can't open CD drivers SHSU-CDN
请教，如何才能在DOS环境中读取光盘中的内容？？？
【问题二】
又想到一个问题。
gyjys给我的是一个包含usb驱动的软驱镜像文件，使用时需要虚拟软驱才行，但虚拟软驱只能在windows中设置并在重启后使用。万一 windows系统进不去了，那这个镜像文件岂不是不能用了（不知道dos中能不能设置使用ima镜像），这样dos中又不能用usb光驱了。
所以，我的问题是，有没有办法直接将这个镜像刻录到自己的光盘上。当bios中设置从光驱启动时，自动加载这个包含usb驱动的启动镜像，从而进入dos，并可以在dos中使用usb光驱。否则系统坏了后，不但要usb光驱还要软驱，有些麻烦啊。
我的usb光驱虽然能启动机器到dos，但不能读入光盘中的内容。所以不知道可不可以？
This is a question I transferred from other forums. Since it involves issues related to CD-ROM drives under DOS and DOS boot disks, I take the liberty to post it here, hoping that the experts of the DOS Union can help me. Thanks.

【Question 1: Solved】
【1】Use an EasyDrive to connect a common CDROM drive to boot the machine. Use the Windows 98 CD. It can boot the machine to DOS, but cannot read the contents of the Windows 98 CD in the CD drive. The screen displays:
Device drivers not found: "OEMCD001"
No valid CDROM device drivers selected
the windows98 setup files were not found
A:\>
List the contents of drive A. They are some.sys.exe - type files. It can be determined that drive A is definitely not a CD-ROM because the contents of the Windows 98 boot CD are not like this; nor is it a hard disk because the hard disk is in NTFS format and cannot be read in DOS.
【2】Use a USB external CD drive (counterfeit IBM DVDROM) to read the Windows 98 CD to boot the machine. It can also boot the machine to DOS, but still cannot read the contents in the CD drive. The screen displays the same as above.
【3】Connect the machine to the USB external CD drive, then connect the Longshine FDD boot USB flash drive, and use the latter FDD to boot the machine. It can boot the machine to DOS, but still cannot read the contents in the CD drive. So in DOS, enter the following command to try to load the CD-ROM drive driver in the DOS environment:
Enter device.com vide-cdd.sys
The screen displays:
IDE/ATAPI CD-ROM Device Drives Version 2.14 10:48:22 02/17/98
Error: No CD-ROM drivers detected at all
Error: Device driver aborts loading
Enter shsucdx.exe
The screen displays:
SHSUCDX can't intall
Can't open CD drivers SHSU-CDN
Please advise, how can I read the contents in the CD-ROM in the DOS environment???
【Question 2】
Another question came to mind.
gyjys gave me a floppy disk image file containing USB drivers. It needs to be virtualized with a floppy disk drive when used, but the virtual floppy disk drive can only be set in Windows and used after restart. In case the Windows system cannot be entered, then this image file can't be used (I don't know if the ima image can be set in DOS), and then the USB CD-ROM cannot be used in DOS.
So, my question is, is there a way to directly burn this image to my own CD-ROM. When the BIOS is set to boot from the CD-ROM, automatically load this boot image containing USB drivers, so as to enter DOS and be able to use the USB CD-ROM in DOS. Otherwise, after the system is broken, not only the USB CD-ROM but also the floppy disk drive is needed, which is a bit troublesome.
My USB CD-ROM can boot the machine to DOS, but cannot read the contents in the CD-ROM. So I don't know if it is possible?
