LiteON CD-RW fails to be detected by BIOS 50% of the time -


Recommended Posts

Posted

I know its not XP related, but BIOS related, here goes:

I recently installed my new LiteON CD-RW in my PC. And found that when the BIOS tries to detect the secondary master it comes up as None. I reboot again and it gets detected.

If it detects as None, then win2k or xp continously makes my HDD light flash full-on when the PC is not in use.

Another problem I'm having is that my floppy refuses to boot anything natively. I tested my Win98 boot disk in Virtual PC (an alternative to VMWare which other people use) and the floppy boots fine (so its not damaged).

Its stressing me out and I feel I'm about to chuck my PC out the window.

Aaron what motherboard and Lite-on model do you have.

Does the bios non detection problem occur on normal reboots or only from a cold boot?

Bios detection problems are sometimes caused by a faulty or flat motherboard battery.If the battery is losing power the CMOS may not remember all your saved settings.

Microstar 6163 with 440BX Chipset, 800MHz Intel P3 Processor

LiteON 24x10x40 CD-RW

The CD-RW sometimes fails to be detected from a normal reboot. On a cold reboot it detects fine (so far... only shutdown completely about 3 times)

Can't be a flat battery, all my settings are as I set them long ago.

Windows Explorer in Win2k and XP act strange too (see attachment) Happens after I browse a lot of folders then this appears out of the blue. Opening another instance of Windows Explorer fixes it, but it does eventually happen again. I ran CHKDSK on both of my hard drives, nothing strange reported.

The File Syntex looks corrupted to me.

Between /desktop and Documents and Settings I see a small square. [/quote:0f3efee546]

MSNwar,You beat me to it,i was just about to post the same thing.

Aaron you say you have run CHKDSK have you also tried [b:0f3efee546]sfc/scannow[/b:0f3efee546] ?

Double check the IDE cable connections and the jumper on the CDRW.

Yes, I get this square everywhere I browse to! My maxtor NTFS partition, maxtor FAT32 partition, and the Fujitsu FAT32 drive. I doubt both drives are corrupt. CHKDSK reports nothing unusual on all three partitions.

Don't think SFC is going to help me here, as I said: I get this error in both win2k and XP, this obviously shows its not an OS fault.

Checked my PC this morning, Both drives are jumpered correctly

LiteON on Secondary Master, jumpered as master.

Mas***a DVD Drive on Secondary Slave, jumpered as slave.

And my Mas***a likes to eject its tray when I reboot to BIOS. it shouldn't do that either.

You say the DVD ejects the tray on reboot,this may be partly what is causing the problem with the CDRW as they share the same channel.

Have you tried the Liteon with the Mats***a disconnected.Do you have the latest firmware for the DVD?Also do you have the latest bios version for your board?

Sorry to ask so many questions Aaron,but you've got some weird problems there. :confused

I'm having trouble trying to find a BIOS for my mobo. Its an MSI-6163 model, but theres three different types on the www.msi.com.tw site. And none of them support my 800Mhz processor (strange?)

SiSoft Sandra 2002 says its an MSI-6163 Mobo with a 440BX chipset. The POST screen also says 440BX at the bottom.

I flashed my LiteON 2 weeks ago to the latest firmware, didn't help with the BIOS detection of the secondary master.

I can't find a firmware update for my DVD drive, the model is: MATs***A DVD-ROM SR-8585

BIOS Virus or Boot Sector Virus. Virus may be like the CIH and stealth into system RAM.

First. Flash the BIOS.

Second. Boot to a: drive with a clean system disk. Run McAafee (free download) or other anti-virus disk that scans the Master Boot Record of the hard drives.

Third and last resort. If it is a CIH type virus it is a stealth virus and can hide code in RAM. Hard Boot to a: drive, swap system diskette with McAafee diskette, Pull RAM, run McAafee.

May also be a Java Virus Exploit. Theres a WinXP Hot Fix Update availabe for this.

Aaron i've just checked and both these 6163 boards support your Pentium.MSI added support after the boards were manufactured.

Follow the links below and just above the picture of the motherboard theres a link for "CPU support",click on that and you'll see your Pentium is supported.

6163 PRO

Ok I've flashed it, and the floppy is able to boot bootable disks now. I have to do more testing to see if the CD-RW is detected after every reboot. so far so good.....
