Say I replace my MB and CPU from intel and
goto an AMD and new MB but keep my old HD,
Floppy and CDROM - will the OS boot up
properly now that the processor changed ?

Thanks

It depends on what you mean by “properly”.

The odds of you making these changes and having it boot into your OS without asking for drivers is very low.

There is a reasonable probability that you may not be able to boot into your OS at all.

Based on what I’ve been reading in this forum, you may not even be able to boot at all.

Why are you doing this?

No, it will Not boot up. Period

If you are going to upgrade anyway, make sure you have all your essential data backed up, what have you got to loose in trying it out. I've swapped motherboards before and things were auto-detected and updated on 98. Having said that, you could look on this as an opportunity to do a fresh install which is often a good thing periodically.

before you upgrade go into safe mode and remove all reaferences to to everything. install your new hardware and it will boot. hopefully when you first boot you will get cd rom support in windows and from there you can install the new mainboard drivers and then reinstall and freshen you drivers for your other things like video and sound.

Why am I doing this ?

I have 30GB HD, decent video card+monitor, CDRW, network card, modem and Floppy on my present PC. I want a PC with more memory, faster CPU.
I Cant do it on my old mobo (AT form factor).
I Need a new mobo, new ATX form factor powersupply + new memory.

Now - I just connect my old HD, FD, CDRW,
(network and modem will come on new mobo)
video & monitor - will OS work with new mobo & CPU ?

All the drivers for CD, video etc are already on the HD ! Only concern is - will there be any thing in OS modules, registry etc which need old CPU to boot up ?? And if so - how do I get it to fix itself
e.g. NT has a repair facility. Does anyone have experience of this type of situation ?

Thanks

Well I don’t know if it will work but I don’t think you will hurt anything to try. I hope you are patient, have a lot of time, and don’t freak out easily.

I think you should first backup any critical information that you have on your current HDD. Locate or download copies of all your drivers. If possible, have another computer running and ready to go to the Internet for further advice and downloads.

Build up your “new” computer piece by piece. Start with one stick of RAM, your CPU, your HDD, your FDD, your CDROM, and your display adapter. If you can get it to boot into your OS, run the new MOBO drivers. This would best be done in SAFE MODE. Then, add one new device and its drivers at a time until you have it built back up. Make sure your reboot after each device is added.

If this turns out to be a disaster, and it might, consider buying a new HDD and starting over with a new OS as IB suggested above. You could add your old HDD as second drive and access your current stuff from the new OS.

There's a simple thing to do in this situ.

Before the last shut down on the old setup, open Regedit and delete the key:

HKEY_LOCAL_MACHINE\Enum

And all it's content.

This gets rid of all the hardware settings pertaining to the old mobo and CPU, and all the memory mapping for the old setup.

When you install the drive on the new board and setup, Windows will be looking for hardware and the right drivers for it, BUT, without nay interferrance from the OLD settings.
You'll need the driver and software disks for all your hard ware not covered by your windows version.
NB: Any hardware newer than your windows version will need outside drivers.
