CONVENTIONAL MEMORY

Please specify what kind of MS-DOS application requires more than 620 Kb of bottom memory!

I guess you are trying to play a DOS game.
The best way to do it:
1) USE a boot disk (floppy disk) to boot up your computer.
a) If it is a dos game: use this command.
in C: prompt
c> sys c: a:
open your wordpad and make two files:
config.sys and autoexec.bat into the disk A:

make the file "config.sys";
add the following lines in it.
device=c:\windows\himem.sys
device=c:\windows\emm386.exe ram
DOS=HIGH,UMB
devicehigh=C:\HXCD-ROM\CDROM.SYS /D:MSCD000
This last line is CD-ROM support; check your own config.sys to see the CD-ROM driver; don't use the same as mine. Copy your CD-ROM driver line command to the last one. But "devicehigh=" is a must; don't just use "device="

make a file: "autoexec.bat"
add this: (for sound card, check your own setting.)
SET BLASTER=A220 I5 D1 T4

b) If you are using a DOS which needs windows environment:
please a floppy disk in A:
go to DOS prompt in win98
cd\windows\system
bootdisk.bat
then it will make a boot disk
