Reload Op System After BIOS Flash????

[SCompRacer]

Read a post elsewhere that recomended a complete op system reload after a BIOS flash.

Reason given was during OS installations, the
setup program reads the register set up by the BIOS. Change the BIOS, the register changes.

SO does this have some merit or not? I never reloaded anything after a BIOS flash and encountered disaster.

Never bothered here either. However I've seen dupclicate entries being loaded under safe mode after the bios has gone from a older type bios to newer one that supports acpi. This slows the system down and tends to cause shutdown problems. However removing these dupclicates and letting windoze redetect everything solves this.

I have visited safe mode from time to time and deleted duplicates devices too. Never put the two together. Thanks for the info!

Ghosting is a fast way to install a os ont a new machine...

And when it is done from a clean master install it's not that bad...

but when the "same" "os" is ghosted from machine to machine to machine funny things show upp when you enter safe mode...

I was contracted to do a system clean of a computer and boted it up in safe mode and found 20 each of diferent cd-roms, monitors, hdd's, modem's, IDE controllers etc etc...

The delete button on the keyboard I was using almost wore out!

On most new motherboards Win 9x will automatically detect the changes and update accordingly ... but that's only when there is some major changes .... on minor changes nothing happens which is OK because no change is needed from the Op.sys point of view.

Actually windows won't detect the changes with a new type of bios. You have to go and remove all the stuff in safe mode like was said, then reboot. When you reboot, not much will be detected, so what needs to be done is add/remove hardware and let it manually detect everything, this way it will find what it needs.

One thing I can't understand is why does windoze suddenly decide to make dupclicate entries when theres been nothing done to the system.

[Rags]

This can happen when you move a device in it's slot, disable it, or make a change in the bios.

there is the easy option... if you know you're going to make some big changes, you can create a new hardware profile, just copy the existing one,.. when you reboot, windows will say it cant work out which one its on, and will re-detect everything

never had to....except

1) flashed bios on a chaintch pentium board so it could ID my k6-233, win95 freaked and refused to boot, even into safe mode. reinstall fiXed it.

2) I flashed the firmware on my adaptec 2940 uw, windows 98 freaked out, for some reason it could not ID the HDD's proerply, win NT 4 and linux booted without a prblem. but inorder to get win98 going I had to reinstall.

They are the only two flashing issues I have had after flashing multiple motherboards,video cards and scsi cards multiple times.
Its also recomened that you run your processor at it standard speed during a bios flash, I don't (k6233 at 250,celery 300 at 450 and a 750 duron at 1G) and havn't had problems yet...lucky?
