Titolo: AIUTOOOO!!!!

Ho l'esigenza di unstallare win 95 su una macchina dove ho un
processore AMD 500
e mi da un errore di protezione IOS. (pare ciò  sia dovuto al
processore).
Mi sono informato e mi hanno detto di scaricare il file AMDK6UPD.EXE.
OK fatto. Questo file deve essere lanciato per forza da win. Il problema
é
che non riesco a far partire win in modalità provvisoria.
Ho trovato un file di spiegazione (nel sito microsoft) dove dicono, nel
caso
win non parte in modalità provv., di digitare al prompt c:/win /d:m
ok fatto a questo punto dovrebbe partire e.......non parte perché mi
chiede di verificare l'esistenza del file HIMEM.SYS nella directory
windows..... fatto il file c'é. A questo punto cosa posso fare!!!!!
Ringrazio chiunque mi sappia dare ulteriori informazioni!!!!
Grazie Roberto

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 indicated
[Image]
processors 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
A supported fix that corrects this problem for Microsoft
Windows 95 OEM Service Release versions 2, 2.1, and 2.5 is
now available from Microsoft, but has not been fully
regression tested and should be applied only to computers
experiencing this specific problem. If you are not severely
affected by this specific problem, Microsoft recommends that
you use the next release of Windows.
To resolve this problem immediately, visit the following
Microsoft Web site:
 
http://www.microsoft.com/windows95/downloads
Scroll down to the Service Packs section and then click the
link to download the Windows 95 Update for AMD-K6-2/350.

   12/04/98  12:13pm  4.00.1213  111,678 bytes   Ntkern.vxd
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:
  1. Download the Amdk6upd.exe file to a floppy disk.
     Download the file from another computer, if necessary.
  2. Restart your computer. When you see the "Starting
     Windows 95" message, press the F8 key, and then choose
     Safe Mode from the Startup menu.
  3. If your computer starts in Safe mode, skip to step 6. If
     you cannot start Windows, continue with step 4.
  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.
  5. At the c:\ prompt, type win /d:m to start Windows in
     Safe mode.
  6. 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.
  7. Follow the instructions on the screen to install the
     update.

 che non riesco a far partire win in modalità provvisoria.
Niente paura. Con il PC spento, riduci la velocità di clock sulla scheda
madre (ci sono dei ponticelli, spostabili, che determinano a che velocità
deve andare), oppure il moltiplicatore del clock (altri ponticelli), in modo
che la velocità ottenuta (clock x moltiplicatore) sia minore di 350.
Riaccendi il PC; installa il file Amdk6upd.exe; spegni; rimetti tutto come
stava e riaccendi; appena Win95 parte urla: "Miracolo!!!" (puoi anche alzare
le braccia al cielo, come faceva Mosè, ma questo trucchetto funziona anche
senza alzarle).
