Things I don't understand:
1: Why can it use upper memory even without loading emm386?

What are these things?

I can't understand these statements.

What I want to modify:
1: Can I add emm386.
2: Use findcd.exe and findramd.exe to locate the drive letters of the CD-ROM and RAM drive. The situation with multiple CD-ROM drives has to be considered.
3: Choose the best programs to use, for example, use VIDE-CDD.SYS for the CD-ROM driver, CTMOUSE.EXE for the mouse driver, DOSLFN.COM for the long filename driver, etc.
Experts please help me, many thanks!!!!

This should be the DOS boot disk that comes with Win98... its features are too limited, and it's also very hard to modify (because there is too much that needs changing). You might as well just download a fairly good DOS boot disk from the “DOS Boot Disk” section and modify that instead...

1. If 1.EMM386.EXE is not loaded, the LH command can still be used, but it has no real meaning, same as not using it.
2. Those commands are from the Win98 boot disk, used to test the machine and install the CD-ROM driver.
3. SET TEMP and SET TMP specify where junk files are stored.
SET EXPAND=YES 'specifies that compressed files can be expanded, meaning those whose extension ends with an "_"
SET DIRCMD=/O:N 'specifies the default parameters of the DIR command, meaning sorting in alphabetical order by filename.

It should be HMA..... as long as HIMEM.SYS is loaded, HMA can be used

They load APSI drivers and SCSI drivers

I learned something again, thanks to the experts above!
