Felmeddelande vid start

Recommended Posts

Jag får följande felmeddelande när jag ska starta Windows 95:

När enhet IOS skulle startas

Fel:En I/O delsystemsdrivrutin startades inte

Antingen är filen i underkatalogen /iosubsys skadad eller så finns det inte tillräckligt med minne

Jag har haft det här problemet en gång förut och då ominstallerade jag windows.Jag har försökt ta bort lite program och strulat lite med config.sys men det funkar inte. Jag har 32 mb ram och 685 mb ledigt diskutrymme. Jag kan starta i felsäkert läge. Vad är felet?

Välkommen till forumet för Windows 98!

 

Uppgradera till Win 98 så löser det sig nog. Annars kan du göra ett inlägg här.

 

Tyvärr är jag bara expert på Windows 98. Kan tyvärr inte hjälpa dig.

Klippt från MS Technet:

 

The information in this article applies to:

 

- Microsoft Windows 95

-------------------------------------------------------------------------------

 

SYMPTOMS

========

 

Under some circumstances Windows 95 may fail to boot, and will display the

following error message:

 

Error: An I/O subsystem driver failed to load Either a file in the .\iosubsys

subdirectory is corrupt or the system is low on memory.

 

CAUSE

=====

 

This problem may occur when all memory below 1MB is allocated prior to

initialization of Ios.vxd. Ios.vxd must allocate memory below 1MB for use as

real-mode buffers. If Ios.vxd can't allocate this memory, it fails to load,

which in turn causes Windows 95 to fail to boot.

 

Memory below 1MB is typically reserved for components that specifically request

it. However, it is possible that Windows 95 will allocate all memory between 1MB

and 16MB during initialization, forcing system DMA buffers (which must lie below

16MB) below 1MB, and therefore preventing Ios.vxd from being able to allocate

memory below 1MB.

 

RESOLUTION

==========

 

This problem can be worked around by adjusting the maximum cache size allocated

by Vcache.vxd. Vcache.vxd allocates an initial cache size that is no larger than

9MB. Setting the maximum cache size to less than 9MB also reduces the initial

cache size, freeing up memory below 16MB and allowing Windows 95 to boot

properly.

 

The maximum cache size is set by adding a "maxfilecache" line to the vcache

section of System.ini. The following example shows what an entry in System.ini

would look like to set the maximum cache size to 6MB:

 

[vcache]

maxfilecache=6144

 

STATUS

======

 

This is a known problem in Windows 95. It has been fixed for Windows 98.
