China DOS Union

ROM-DOS is a very powerful and practical DOS. It not only has good stability and compatibility, but also locally supports long file names, FAT32, and various other tools and software development kits (SDK). Now the boot disk download of it is provided:

Note: This is an enhanced version modified from the original ROM-DOS boot disk I made. It adds creating a memory virtual disk with XMSDSK, and using the practical FINDRAMD program mentioned by netizen baobolz to find the drive where the memory disk is located, and the function of copying the COMMAND.COM file to the memory disk. Especially Teacher Mo can take a look at this function for finding the memory disk.

Moderator, I downloaded it and it's really fast. I also unpacked it to look at the source code inside, but I don't understand a lot. Can you be patient and explain to me? Can you give me the detailed functions of these commands?
break on
lfnfor on

break on Press the Pause key to interrupt
lfnfor on Support long filenames
verify on Support verification, such as when copying
set dircmd=/OGN /4 Set parameters for the DIR command
set comspec=a:\command.com Set command processor path
path=a:\;.. Set search path
mode con rate=32 delay=1 Keyboard speed
killer.exe Memory-resident program to interrupt the operation of some programs
doskey.com Need I say more?!
mscdex.exe /D:CDROM1 /K
ctmouse.exe /r3 Mouse
set ramdrive=xmsdsk 1024 /y Set virtual disk
findramd>nul Find virtual disk
if %ramdrive%#==# goto noram Judge virtual drive letter
copy command.com %ramdrive%\>nul Copy command processor to virtual disk to speed up response
path=%ramdrive%\;%path% Add virtual disk path
set comspec=%ramdrive%\command.com Set command processor path
:noram

GOOD, I downloaded it, must try it.

It can be seen that now the ROM-DOS bootable disk has reached the stage where it can be actually mass-produced.

This time I made some more modifications, for example, deleting the useless COMMAND.HLP, adding the practical MOUSCLIP (a small tool for mouse copy/paste under DOS), replacing MS's MSCDEX with CLOAKING+MSCDEX that only takes up 4K of memory, replacing the original HIMEM with FreeDOS's HIMEM and DR-DOS's EMM386 to support XMS memory above 64M (up to 4G at most) and provide 32M of EMS memory, etc. Download here:

Some netizens reported that they couldn't download from this address. Now re - upload it to the forum:

Can the boot disk of ROM-DOS be used in MS-DOS?
Also, I haven't installed ROM-DOS. Do I just need to extract the files in the compressed package to the floppy disk to use it, or do I need to use SYS to transfer system files under ROM-DOS like in MS-DOS!

ROM-DOS and MS-DOS are two different but mutually compatible DOS operating systems. Of course, one cannot be used within the other. Just boot from a floppy disk.

There is incompatibility between r-dos and diskgen. Is there a way to solve it?

I just tried running DiskGen under ROM-DOS 7.10 (on drive C), but didn't find any incompatibility. Besides, DiskGen is rarely used.

I made a boot disk with the core startup file of r-dos710. Running diskgen in it restarts. spfdisk is okay. Also, please tell me in detail about minicmd.com?

If there is a reboot, then I estimate it's a configuration problem. You can check files like CONFIG.SYS, etc. minicom.com is a miniature COMMAND.COM command processor, very compact, but I haven't used it much either.

Can command be replaced? Otherwise, what's the use?

MiniCMD is not suitable to replace COMMAND under normal circumstances because its characteristic is being small but not very practical, unless there are special purposes.
