Thinkpad 755cd BIOS not detect the internal cdrom drive

[Volky1969]

Hi everyone;

I have a thinkpad 755cd full upgrade. The problem is that when I install the internal cdrom drive, the laptop not detect this cd. I go to EZsetup and the cd icon is grayed. I make all the diagnostics and everything is OK!. I put the diagnostic diskette and everything is OK too. The test for system board show an OK! However windows 98 detect something and install the corresponding driver for this cdrom drive, but says that the device is not working, not present or all drivers are not installed. The cdrom drive is fully working because I have another 755cd and test it, works great. The BIOS is latest upgrade. The floppy works great!. In the device manager the corresponding Standard IDE/ESDI Hard Disk Controller with irq and i/o range for this cd is showed, but not a cdrom drive. Please let me know any ideas to use my cd again. I need to buy another system board? If is so, where can I buy one preferably new? I appreciate any help. Thanks a lot and sorry for my poor english.

I know this post I'm replying to is pretty old, but I'm having the same problem now. Volky1969, did you find a solution, or does anyone else have any ideas.

Also, I haven't been able to figure out why IBM doesn't have the 755 on their driver download matrix at this link:

Anyone know?

Your 755, my 750 and all the 760's and other machines have been taken off because they are just too old. There are ways to get to some of the files though, like the driver matrixes often still have links.
