Hi,

I found Windows95/98 driver for mentioned model only. If I created XP boot floppy and used the floppy to boot up the PC, the Matsushita CD drive couldn't be accessed. Please suggest what should be done to CD support to the XP boot floppy ?

Tks!

You might have found a driver that was stated as being for Windows 95/98 but that statement is untrue. Microsoft designed all Windows os's, starting with Windows 95, to support optical drives natively. In reality, no drivers exist for Windows os's and no drivers are needed. If they're not needed then why would such a driver exist? Any driver you find can only be for pure DOS mode since that's the only os where one is needed. Should not even be used if you're running any Windows os from 95 up. Allowing a DOS driver to load while Windows is running will most certainly get you a "dos compatibility mode" error problem and cause havoc on a Windows machine.

Why would you even want to boot up with a floppy disk? Doesn't your bios support booting from a CD-ROM drive?
Most all motherboards built in the last 5 years will do so.

I don't understand your question. Do you mean instead "what can I do to enable my cd-rom drive when booting from a floppy"? If so, the answer is put DOS cd-rom drive boot files on the boot floppy disk, eg: oakcdrom.sys and mscdex.exe and have both load using command lines in autoexec.bat and config.sys files.
Or do you mean instead "how to I boot from a cd-rom disk like Windows XP? If so, the answer is simple, change the settings in bios setup to "boot from cd-rom drive first" or "enable cd drive as first boot device". That way it will boot directly from the XP install disk. However, you must have a modern bios in your motherboard for this to work, eg: your bios must have this support option. If it doesn't, I doubt your system will even run Windows XP (or it's in severe need of updating).

I know BIOS can support boot from CD but that function could fail. I met one motherboard with this problem and I couldn't throw away this board just because this single function failed.

Yes, I mean "what can I do to enable my cd-rom drive when booting from a floppy".

comptuerhope.com suggested below change to autoexc.bat & config.sys

http://www.computerhope.com/boot.htm#08

[autoexec.bat]
@echo off
LH A:\MSCDEX.EXE /D:CDROM

[config.sys]
device=a:\himem.sys
dos=high,umb
device=a:\emm386.exe noems
files=30
buffers=20
devicehigh=a:\oakcdrom.sys /d:CDROM

However, mscdex.exe, emm386.exe were not found from under installed Windows XP directory \WINDOWS. I need to copy that files from installed WinME directory. What is worst, the boot up hang up before it completes. I don't know which line in the files caused the hang up.

the following comands work fine for me:

[autoexec.bat]
mscdex.exe /d:cdrom

[config.sys]
device=himem.sys
device=oakcdrom.sys /d:cdrom

naturally you won't see where it fails because of your first command line: eg: @echo off
change it to read: @echo on in order to see each command line executed on your screeen. Or just simply delete that command line.

Thank you very much, it worked for my computers. I could access Rioch, SONY, Memorex, LG CD/DVD drives with this boot disk. I remembered I had made one similar boot disk for my notebook installed with ME but I forgot that oakcdrom.sys was a general purpose CD-ROM driver. Actually, all the mscdex.exe, himem.sys, oakcdrom.sys were copied from my ME installation. Before modifying autoexec.bat & config.sys, I'm anxious about whether the boot floppy created from XP could make use of Extended memory properly. The result convinced me that XP did it well !
