Here's a detailed description of my problem. The BIOS that I am running is Award Medallion BIOS v 6.0, Asus A7V ACPI BIOS Revision 1005C. Please let me know what I should do to get the CD-ROM/DVD-ROM to be recognized!  During system startup, the computer tries to auto-detect Primary Master, Primary Slave, Secondary Master and Secondary Slave but finds “None” for each of them even though all are set to auto-detect in the BIOS  The boot sequence set in the BIOS is 1. Removable floppy device, 2. ATAPI CD-ROM, 3. IDE Hard Drive  The C: drive has been formatted and now contains the following: C:\WINDOWS\COMMAND contains the MSCDEX.exe file C:\PIONEER contains the DVD-ROM driver ATAPI_CD.SYS The contents of C:\CONFIG.SYS are: DEVICE=C:\PIONEER\ATAPI_CD.SYS /D:MSCD001 The contents of C:\AUTOEXEC.BAT are: LH C:\WINDOWS\COMMAND\MSCDEX.exe /D:MSCD001  The system is booted with the Windows ME Startup disk. The disk contains the DVD-ROM driver in the root, A:\ATAPI_CD.SYS. The contents of A:\CONFIG.SYS are: [menu] menuitem=HELP, Help menuitem=CD, Start computer with CD-ROM support. menuitem=NOCD, Start computer without CD-ROM support. menuitem=QUICK, Minimal Boot menudefault=HELP,30 menucolor=7,0 [HELP] REM device=oakcdrom.sys /D:mscd001 device=atapi_cd.sys /D:mscd001 device=btdosm.sys device=flashpt.sys device=btcdrom.sys /D:mscd001 device=aspi2dos.sys device=aspi8dos.sys device=aspi4dos.sys device=aspi8u2.sys device=aspicd.sys /D:mscd001 devicehigh=ramdrive.sys /E 2048 [CD] REM device=oakcdrom.sys /D:mscd001 device=atapi_cd.sys /D:mscd001 device=btdosm.sys device=flashpt.sys device=btcdrom.sys /D:mscd001 device=aspi2dos.sys device=aspi8dos.sys device=aspi4dos.sys device=aspi8u2.sys device=aspicd.sys /D:mscd001 devicehigh=ramdrive.sys /E 2048 [NOCD] devicehigh=ramdrive.sys /E 2048 [QUICK] [COMMON] files=10 buffers=10 dos=high,umb stacks=9,256 lastdrive=z device=display.sys con=(ega,,1) country=004,850,country.sys install=mode.com con cp prepare=((850) ega.cpi) install=mode.com con cp select=850 The contents of A:\autoexec.bat are: @ECHO OFF path=c:\windows;c:\windows\command \hibinv.exe call \checksr.bat IF "%config%"=="QUICK" GOTO QUICK set EXPAND=YES SET DIRCMD=/O:N set LglDrv=27 * 26 Z 25 Y 24 X 23 W 22 V 21 U 20 T 19 S 18 R 17 Q 16 P 15 set LglDrv=%LglDrv% O 14 N 13 M 12 L 11 K 10 J 9 I 8 H 7 G 6 F 5 E 4 D 3 C cls call setramd.bat %LglDrv% set temp=c:\ set tmp=c:\ path=%RAMD%:\;a:\;%path%;%CDROM%:\ copy command.com %RAMD%:\ > NUL set comspec=%RAMD%:\command.com copy extract.exe %RAMD%:\ > NUL copy readme.txt %RAMD%:\ > NUL :ERROR IF EXIST ebd.cab GOTO EXT echo Please insert Windows Millennium Edition Startup Disk 2 echo. pause GOTO ERROR :EXT %RAMD%:\extract /y /e /l %RAMD%: ebd.cab > NUL echo The diagnostic tools were successfully loaded to drive %RAMD%. echo.

So what happens when you boot up with the boot disk - do you get to an A:/ prompt ? And if you boot up without the floppy, where does that take you to ? If you get to a C:/ prompt, then can you get a file listing if you type DIR If no IDE devices are detected during startup, then do you ever get into Windows ? Krystyna

Yes, I do get an A:/prompt when I boot with the floppy. If I boot up without the floppy, the boot doesn't work (although this is fixed now that sys files are copied to c:). Yes, I can get a directory listing at the c: prompt. Before I could get into Windows even though no IDE devices were detected during startup (of course, now Windows is not on c: after the format). The problem may be a problem with the BIOS update that was done, so the BIOS is going to be updated again. Any other ideas?

When you boot with the ME boot disk, do you choose to start with CDROM support ? This should take you to an A:/ prompt Depending on how many HDDs and partitions you have, the next letter will be for the virtual RAMDRIVE that the boot disk sets up. eg if C: is your only HDD, than the virtual drive will be D: and your CD/DVD ROM will now be E: Once Windows is installed, the virtual drive is discarded, and the CDROM should appear in Windows as D: If it doesn't happen like this, then perhaps the BIOS is at fault, or then it could be a dodgy boot disk. When you set the devices to be autodetected, did you save the changes before exiting the BIOS ? Krystyna

Try in the bios: first boot device cd rom succes
