"Window protection error' on Win98 startup
Recently I bought a used HP L1502 15" LCD monitor for use with my old faithful PI-180mhz. It was working well. The only drawback was the display adaptor was not able to fully utilised the native resolution 1024x768 of the LCD monitor. No complaint.
Later I decided it was high time to upgrade to faster CPU. I bought a partial system - PIII-933mhz, 256MB PC-133 SDRAM, MSI-6368 motherboard, with HDD. It was working perfectly on Win98 when I bought it.
Back home, I reformatted the HDD and reinstalled Win98 afresh. After all OS files were copied and system reboot to run Win98 for the first time, it started to search for installed hardware. I saw something like "L1502 .....monitor" displayed on screen for half a second, it proceeded to search for driver to install "Plug and Play Monitor". At this point the screen blackened off, then it displayed "Window Protection Error - you need to restart system. Press any key to continue". I pressed a key, it rebooted and ran the same sequence and hang at the search for driver to install "Plug and Play Monitor" screen with the mouse pointer freezed. I rebooted many times, sometimes it paused at "Window Protection Error" and allowed reboot at touch of any key; sometimes it completely freezed at search for driver screen not responding to power button but only to reset button. A few times, I press 'tab' key then 'enter' key immediately after seeing the "L1502 .....monitor" screen in an attempt to cancel the search for "Plug and Play Monitor" driver action, I managed to reach the 'Welcome to Window 98' screen but system would still freezed after that.
I pressed F8 to boot up in safe mode. At 'My Computer'- properties- device manager, I did not see monitor on the list. So I cannot update driver manually for the monitor. At 'Display' - properties-setting-advance, there are tab for general, adaptor and performance but no tab for monitor. Under adaptor, I changed it with the display driver downloaded from the motherboard manufacturer (MSI)website. I also install Chipset driver for the motherboard. All done to no avail.
As last resort, I wiped off c: clean and install Win95OSR2.0 It worked! Win95 installed did not recognised the L1502 monitor, it dumbly installed as a standard VGA adaptor with a Plug n Play monitor and all other hardwares without a hitch. Subsequently, under 'My Computer'-properties-device manager I updated all the drivers. Now it works perfectly but in Win95 and showing CPU as Pentium Pro instead of P!!!.
How come an older OS can work while a newer OS keep dying on me? The Win98 was smart enought to recognise the new L1502 but did not allow manual intervention to complete the driver installation. The Win95 was dumb but at least it set things up and running to allows subsequent update.
Now my question is:
If I install Win98 over Win95 now, without HDD reformat, will it only upgrade OS while keeping all working installed drivers intact? In other words, will it work and not revert back to square one - with all the window protection error?
If it does revert, what is your suggested solution to help me run in Win98?
