Ich habe einen PC AMD 400 mit bei Auktionen gesteigerten Teilen zusammengebaut. Nach installieren von Windows 95 oder 98 erhalte ich jedesmal die Meldung "Beim Initialiesieren des Geräts IOS: Windows-Schutzfehler - Starten Sie den Computer neu". Diese Meldung erscheint immer wieder, auch im abgesicherten Modus. Andere Einstellungen im Bios waren bisher erfolglos. Wer kann mir helfen?

Problems Using High Speed AMD K6-2/350 Central Processing Unit
Micrrosoft Windows 95
Microsoft Windows 95 OEM Service Release versions 2, 2.1, 2.5
Symptoms
When you start your Windows 95-based or Windows 95 OEM Service Release- based computer that is using an AMD-K6-2 processor that runs at a speed of 350 MHz or faster, you may receive one of the following error messages:
Device IOS failed to initialize. Windows Protection Error. You must reboot your computer.
Windows Protection Error. You must reboot your computer.
NOTE: This problem is very intermittent at 350 MHz, but occurs more often at higher speeds.
CAUSE
The first error message is a result of a divide exception in Ios.vxd; the second is due to a similar error within Esdi_506.pdr or Scsiport.pdr.
The original released versions of the files listed in the "Resolution" section of this article contain initialization timing loops that do not execute properly on the AMD-K6-2 processor at speeds of 350 MHz and faster. Note that this problem is due to limitations of the software algorithms, and is not indicative of a problem with the processor itself, which is functioning properly.
RESOLUTION
The AMD-K6-2 update has been revised to incorporate a newer version of Vfbackup.vxd file. For information about this update, please see the following article in the Microsoft Knowledge Base:
Q234259 Revision To AMD K6-2/350 Central Processing Unit Update

NOTE: This fix does not correct the problem for the retail version of Windows 95. In addition, versions of the Amdk6upd.exe update dated "09/18/98 11:00am" do not replace the Ntkern.vxd file in OSR 2.1 and OSR 2.5. To determine the version of the Ntkern.vxd file installed on your computer, right-click the Ntkern.vxd file in the Windows\System\Vmm32 folder, click Properties, and then click the Version tab. If the version number is not 4.03.1213, you should obtain and install a new version of the update, as described below. Note that the version of the original Ntkern.vxd file is 4.03.1212.
To install this update, follow these steps:
Download the Amdk6upd.exe file to a floppy disk. Download the file from another computer, if necessary.
Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Safe Mode from the Startup menu.
If your computer starts in Safe mode, skip to step 6. If you cannot start Windows, continue with step 4.
Restart your computer. When you see the "Starting Windows 95" message, press the F8 key, and then choose Command Prompt Only from the Startup menu.
At the c:\ prompt, type win /d:m to start Windows in Safe mode.
Insert the floppy disk containing the Amdk6upd.exe file you downloaded in step 1, and then use Windows Explorer or My Computer to double-click the file.
