Resetting Harware Detection
Hi,
for a school with about 60 Systems (inhomognous) I have created a master system based on Windows98. before imaging I want to reset the hardware-information. There is a RegKey that can be set and Win98 forgets everything and starts from scratch with the detection. The person who knows the key is on vacation, but I need it asap. It is not "CurrentVersion\SetupFlags" !!! If anyone knows this key, please answer! BR. Matthias |

Resetting Harware Detection
Hi,
I am not sure that this is the key I am looking for, but I gave it a try. I deleted the whole enum-tree in the VirtualPC-W98. The system complained about misconfigured graphics adapter and after a series of "enter" the hardware detection started. In the background the loading of the desktop continued. Should I use that with "SetupFlags" (increasing the first byte by 1) to start the detection automatically? Any other hints? BR. Matthias |

Resetting Harware Detection
There was no mention of Virtual PC in your initial post. There are enough
differences between the way that virtual W98 and regular W98 systems work that I would be hesitant to take any shortcuts. I have both on this machine and virtual detected the graphics card on its own (not sure how that works--maybe it piggy backed off from XP?) while the regular required the manual update of the driver. An old printer and scanner will work on the regular W98 load by not on the virtual load. Wiping out ENUM wipes out all the hardware information and the system can hopefully detect the hardware at the next boot. This is a shortcut that doesn't always work right and I would not use it but then I don't maintain 60 different computers and maybe I would change my mind if I did. I don't know the flag answer. For what it's worth, as an experiment, I took a hard drive out of one PC and put it in another with completely different hardware. I have done this four times with different computers involved. I did not wipe out ENUM and surprisingly to me (I had been told it would not work), the hardware detected and the PCs worked correctly. I don't know what would have happened had I used the systems for a length of time--maybe severe problems would have ensued. -- Regards Ron Badour, MS MVP for W98 Tips: http://home.satx.rr.com/badour Knowledge Base Info: http://support.microsoft.com/default.aspx?pr=kbinfo "Matthias" wrote in message ...

This is what we did til now (take an image and push it to the next machine) but we always had to add some drivers manually, and esp the new drivers for the motherboard were most difficult. I now added the drivers in advance and hope to get better results. I will do some tests |

I now added the drivers in advance and hope to get better results. I will do some tests One thing you might care to try: On the master installation, set up a second hardware profile ... this can be anything, just make it a direct copy of the existing profile. This forces Windows to ask, at boot time, which profile you wish to use. Obligingly, it also gives you the option (roughly translated) "none of the above". If you select this latter option, it doesn't have a hardware profile to run with so it will proceed to redetect all the hardware on the system it finds itself in. Once you are up and running, you can then delete the original two profiles. I've always preferred this method, over registry surgery, when changing motherboards since no data is deleted and, if you run into serious trouble (new MB has a problem etc) you can re-install the original MB with no trouble because its profile is retained. It may help in your situation too. I'd also suggest, when using this method, that you eliminate the most troublesome drivers before making the switch ... i.e. the video driver (switch to generic windows video driver) and sound driver (remove). Probably paranoia actually, since the hardware redetection should take care of it, but it doesn't take much. |
