Don't call me any master. I still have many questions I don't understand myself. I don't have QQ. Besides, it's better to discuss problems on the forum. In this way, more people see it and the chance for you to get help is more.

From your previous description, I don't know how your CD - ROM boot is configured. I tell you to boot with the default DOS configuration and then see if there will be the phenomenon that E: is the CD - ROM, that is, boot by skipping CONFIG.SYS and AUTOEXEC.BAT. Have you tried it?

The line LASTDRIVE is not written in the batch file, but in the CONFIG.SYS file. But your situation has nothing to do with whether you write it or not.

Please enter DOS, then execute:
gdisk 1
Or, execute under Windows:
gdisk32 1

Then feed back the result of the command here, or you can also use partition software like Diskgen under Windows to display your partition situation, then take a screenshot and send it here.

First, you must clearly feed back the real hard disk partition information to provide the basis for judging the cause of the problem. I always feel your statement is unreliable.

In addition, you should copy and paste the contents of config.sys and autoexec.bat of the CD-booted DOS as they are (also, please state the version of DOS you are using, which can be found with the ver command under DOS).

Thanks, my question above has been clarified under the guidance of peers, that is, the DOS boot has been solved. Now there is one thing to ask. I want to use EASYBOOT to edit four recovery files (needing to use DOS boot), namely automatic recovery for Inspur machines, Lenovo machines, Great Wall machines, and DELL machines, and the GHOST of each machine has been done, but I don't know the association between the secondary boot and primary boot of EASYBOOT. Please give me some guidance. I don't know how to start, or which articles on the Internet to look at, thanks.

Everyone has been paying attention to the problem you encountered, but now you're bringing up the issue of making a GHOST recovery CD, which is quite disappointing. At least, you should first tell others where your problem was and how you solved it. It's not in vain that everyone cared, and it's also meaningful for others who encounter the same problem.

Your current approach is quite annoying.

1. Is your DOS boot disk version 6.22 or something else? Version 6.22 doesn't recognize FAT32 (not FAT, FAT can only be up to 2.1G), so it has no relation to 40G partitions or 160G hard drives.
2. Since your 1G 71084A can recognize, the problem is simple. You can use arj or rar (versions 2.9 and earlier) to compress or split the target file, and you can complete the backup in one time (最多 two times) at most.
PS: Since the machine where you store the 1.09G file may not necessarily have enough free space, you may need to point the source parameter to the disk and path of the 1.09G and the target parameter to the disk of the 71084A when using arj or rar.
BTW: Remember to format the 1G Diamond hard drive to FAT. FAT32 is meaningless for it and can only cause more compatibility issues.
3. Early machines didn't support LBA48. According to the current hard drives on the market, the maximum support is up to 120G (theoretically supports below 137G).

First, it may be that the DOS 6.2 version is too low to recognize the large hard disk. Second, the DOS version above 7.0 can normally view the F drive. Third, since the optical drives of current machines are all four-wire, the DOS version above 7.0 can simulate the A drive to drive the optical drive. I don't know the reason why it just can't read some additional programs or files in the CD. That is to say, it only recognizes the simulated A drive, and can read the content of DOS programs under DOS, but just doesn't recognize the actual CD drive letter, not even entering it. I suspect it is a problem with the optical drive driver program. I have already ruined several DVD discs, and it is of no use. I will avoid it for a while. The elderly are sick and hospitalized these two days, so I don't have time to play. You all play first. I will study it when I have time. Thank you for everyone's support.

Four-wire CD-ROM? That's a SATA CD-ROM, and there's probably no driver under DOS.
