Primary and Secondary IDE controller not working

[coil]

My computer fails to recognize the CDROM. I have a generic intel pentium 200 computer with an intel triton vx chipset on a jbond motherboard. It has be working fine for the past year but yesterday it failed to recognize the cdrom. On boot up it finds the cdrom but I can not access it after win98 loads. Under system devices, the primary and secondary ide controllers are not working, there are yellow "!" by them. My hard drive works fine. I tried deleting the controller device and windows reloaded the driver but I got the same results. I also switched cdroms but no help. Any suggestions

Losing your HD controllers in WIN is one of the symptoms of a virus. Do you have a virus scanner installed?

Hi, Coil! As Susan says, it could be a virus or any other device conflicting with the ide controller. Run an antivirus...and check again. If the antivirus does not work, remove all the devices and peripherals. The plug and play will fix the problem.If it is a hardware problem, you can buy a pci ide controller card for around $35.00. It is cheaper than a new motherboard. Good luck!

I have McAfee VisusScan with the latest dat file (7/15/99). No virus found. I tried rebooting in the MSDOS mode and I am able to access my cdrom drive. I must have a conflict although I did not change any settings or add any hardware. Other than the yellow "!" by the Intel 82371SB Controller, there is no indication in system/devices that anything is wrong. I have tried to delete devices but the computer locks up when I delete the IDE controller.

First try downloading and installing Intel's latest busmaster driver; http://developer.intel.com/design/chipsets/drivers/busmastr

didn't clear it up??


It still sounds like it could be a boot sector virus to me:

Try this: using a virus free start up disk that is write protected boot the computer and type in fdisk /mbr at the command prompt and press enter. Next type in sys c: and press enter. Now reboot.

if the problem is due to a virus that should fix it for now ..If the problem is fixed (temporarily) you will need better anti virus software.

didn't fix it?

run regedit and do a search for the "noide" key, remove it and reboot...

Now if any of the above great suggestions don't work, try this. Do a safe mode boot and go into device manager and look for exact duplicate entries in there. If any are present, delete them BOTH. Especially look under hard disk controllers. Anyway go through all categories checking for the same thing.

Let us know what happens.

Here's another idea:
Are you loading your cdrom drivers on boot-up, some drivers cause MS-DOS compatibility mode errors and will give you the condition your describing.
Look under the performance tab of your System Properties screen, if your running in this mode you either have one of these present.

1.) You updated your Bus mastering drivers and there not fully compatible with your chipset.
2.) Your Dos cdrom drivers are loading on boot-up and are not compatible with the bus mastering drivers.

I went through this on my computer. I don't upgrade board drivers anymore, if its working.
