China DOS Union

Just install it with a virtual machine, although it’s a bit slower.

Use Spfdisk. First partition, and note that you need to create 3 primary partitions (if you want to install 98, 2000, and DOS), then install its multi-system management function, and that’s it

I’ve already installed 98 and 2000
I still want to install a dos under the g drive

Wouldn’t it be better to just use the MS-DOS 7.10 that comes with Win98?

You have to use Spfdisk to create another primary partition, for example by deleting the extended partition, but be sure to back it up ：）

I suggest not installing it. I’m afraid you won’t be able to handle it.
If you want to learn DOS, one option is to use a virtual machine.
Second, you can use a DOS boot disk. Put (that is, copy) some DOS software onto your G drive, then when you want to use it, boot with the DOS boot disk and go into the G drive to play with DOS.
Third, win98 can enter DOS mode in the first place (win98 comes with dos7.10). If you want to play with more DOS software, when entering win98 choose to enter DOS mode, then go into your G drive and play.

That’s true too; one careless move and then... ：（ I once very “carefully” wiped out a large amount of data on a hard drive, hehe

That scary???

I want to play with that thing called freedos

I played with that 98 dos and now I can’t even get into 98

By the way, I changed BootGUI in msdos.sys to 0 and entered this dos that way. Is it pure or not?
(What is this about dos being pure or not pure)

I suggest you go read wengier’s DOS articles first!
DOS isn’t scary.
It’s just that you shouldn’t casually try some low-level things when you haven’t understood them. For example partitioning, formatting, and multi-system boot management. (fdisk,format,system commander and commands or software with similar functions)
DOS is basically all “green software”! How could it be scary?
As for your saying you can’t get into win98, I believe you’ll soon understand where the problem is. Read more materials!
It’s not DOS’s fault...

I can get in now. I remember that when running cardware I changed config.sys
I looked at my classmate’s config.sys again and it was empty
So I deleted all the contents inside it, and then it was fine
The contents were like this
FILES=20
device=G:\NET\ifshlp.sys
LASTDRIVE=Z

By the way, can I install another 98 on the g drive, then delete windows and leave dos in it
Would that make an option appear in the boot menu

win2k’s os loader will do it, and there’s no need to modify the mbr either, quite safe.

I don’t understand

Hehe, another advantage of using SPFDISK is that if the MBR gets damaged, you can still use it to restore it. (ＳＰＦＤＩＳＫ puts the original ＭＢＲ in another hidden sector: for example the third sector in ＳＰＦＤＩＳＫ Ｖ９８２Ａ; I haven’t analyzed the others)

The latest version of SPFDISK is VER 3D, all in Chinese, and it’s really easy to use. 80% of the machines in my company that have multiple systems all use it. A few days ago, on that PC of ours (Pentium 266, pretty lousy, right! ^_^), somehow the hard drive’s MBR got killed. There were my 300M of materials on it, as well as company files. C, D, and E all couldn’t be entered. Fortunately we had it, and the hard drive was rescued. I previously analyzed the MBR made by SPFDISK’s VER 98a version; it moves the original MBR to the third hidden sector of the hard drive. I thought its VER 3D version wouldn’t be bad either, so I fixed my HD very easily, amen!
