CD-Rom speed

[bearnoy]

I'm having trouble with my CD-Rom drive the manual says that its capable of Dma33 but I'm only getting Pio mode 4 my jumper is set to master and I check the manufacturer web site for help but found no information whatsoever about my CD-Rom,this is the model: E-IDE CD-ROM CR-852E,the box says that its manufacturer by CTX but nowhere on there website mentions CD-Rom.Thanks for the help.

Look for the FCC ID number on the cd-rom, and then post it here. I'll try and look it up..CTX uses OEM parts the model 852E sounds like it a Teac, but I don't know for sure... <IMG SRC="smilies/redface.gif" border="0">

What Motherboard and system specs do you have??
Depending what you have for system specs, sometimes older mb's only supported up to mode4, Your cd-rom maybe capable of u-33 speeds, doesn't mean the board will.
May be in the bios there is a setting for u-33 support and it might just be disabled.

This is my motherboard spec:Gigabyte Ga 7zx,AMD Thunder Bird 850,seagate 10.4G ATA66,52x CD-Rom,128mb ram,Geforce2mx.Could it be that I'm not using the right cable for it?

Gigabyte 7zx-(1)?? right?
If that is the correct board you gave me and your cd-rom is on the 2nd ide controller, you need a bios flash update to correct the issue of it seeing mode 4 instead of u-33.
here's the link to download the bios:

Hope you are familiar with proper bios flashing procedures and the risks involved.
Use a clean boot disk with no himem.sys, emm386.exe, etc. and unzip the flash to the boot disk.
In case I gave you the wrong link, here's to the giga-byte support page just to make sure and select your own flash.

Good luck!

P.S. Maybe also load the latest via 4.31 patch for your board and os at www.viahardware.com (http://www.viahardware.com) and don't use that beta bios for your board from the gigabyte web site if you browse there. I linked you with the latest official bios update on your board, assuming that is the right board you listed.
Bye for now.
