PLEASE SUPPLY RELEVANT INFORMATION:
Operating System Version:  English win98, Chinese win98
Problem Application Name & Version:
Problem Hardware Make & Model:
Error Messages: Need to reinstall windows


hi all, need some advice on my uncle's computer.
It's a dual boot system running a eng and chinese win98
The problem is with eng win98.  I can only boot up in safe mode, otherwise is says that some file is missing and i need to reinstall.
The file in question in a drv file related to the isp they are using.
I've tried looking for that file on the installation disk provided (doesn't exist), uninstalling the ISP's program with no success.
The error message remains the same.

So the question is, do i need to reinstall win98 to solve this problem? if so, i'm not sure how as safe mode doesn't support the cd-rom drive.

Hi,

Please let me know what the missing files are so I can tell you if re-installing Windows will correct this.

Hi,

Since the problem is with a third party software (the ISP stuff), I doubt that re-installing Win98 on top of what's there will fix the problem because the entry for that file would remain in the registry.

Try searching the registry for cfos20.drv and remove any keys relating to it.

IMPORTANT: Make sure you backup your registry before doing anything

1. Start > Run
2. Type 'regedit' (no quotes) then OK
3. Select File > Export
4. Set the Export Range to ALL (at bottom)
5. Give it a filename and find a location on your C: drive for it.
6. Hit 'Save'

Then do Edit > Find and look for cfos20.drv
Delete the keys that have references to this file.

When you un-installed the ISP software "with no success" do you mean the uninstall failed part way or right at the beginning?

hi,
just had a try looking in the registry and came back with no references.

when I un-installed the software, it failed part-way through it.  Think the message was along the lines of 'uninstall incomplete' or 'uninstall not successful'.

May give you an insight?

'cFos' device driver receives the usual modem commands, the so-called AT commands from the communication programs and turns them into the corresponding ISDN CAPI commands. ISDN CAPI responses are turned into modem responses of the same meaning, so that the communication programs 'understand' them.

As you can enter any equipment names (e.g.: ISDN1) or several COM ports (a maximum of two in the shareware version, up to 30 in 'cFos Professional'). Be careful not to enter COM ports that actually exist as hardware and are in use (e.g. a COM port for your mouse).

<<=NOTE=>> The CFOS.SYS driver should be loaded after drivers for serial interfaces (COM.SYS oder SIO.SYS) and after the CAPI driver.

Hi,

Start > Run
Type 'msconfig' (no quotes) then OK
Check Startup tab to see if the cfos20.drv is loading and uncheck that line

Thanks admin,
tried looking for the cfos20.drv under the startup tab but wasn't there, so I checked the other tabs.  Finally found it under the system.ini tab under the boot folder.
I've always wondered where to find all the bootup commands.
Anyway, the system seems to be running atm.
Thanks again for the help!!
