Hi, I'm hoping you can help me. I'm pretty stuck on this question.
I couldn't figure out why a computer was locking up during its startup process. Upon examining the bootlog, I found that on the 2nd time that esdi_506.pdr tried to init my computer froze. When I removed the file from the system, it booted normally. However, I did not have a CD-ROM and my C-drive was running in compatability mode (yellow exclamation marks on primary & secondary IDE channels, error code 10 on drivers, most likely because I removed esdi_506.pdr in order to get the computer to boot). I then turned to google.com to help me find my answer by searching for "esdi_506.pdr" and found a computing.net forum, which linked me to the following microsoft knowledge base article:
MS-DOS Compatibility Mode Problems with PCI IDE Controllers
http://support.microsoft.com/default.aspx?scid=http://support.microsoft.com:80/support/kb/articles/q151/9/11.asp&NoWebContent=1However, upon searching the registry, I was unable to find a NOIDE value like the article above told me to. I've tried reinstalling the controller twice, and switching its type. I've tried changing CD-ROM drives. I've also tried switching hard drives (between a new 40 GB WD drive and an older 6.4 GB Maxtor drive).
As a side note, when I got this computer, it was freezing at the DMI screen. . . an fdisk /mbr took care of that, but I believe that that is also related to IDE devices. Then again, maybe it's not. Just thought I'd throw that in there.
System specs:
Brand - Quantum
RAM - 64MB
Processor - 200 Mhz Pentium I
OS - Win 98 SE (Have also tried Win 95 and Win 98)
Video Card - Diamond 3D 4MB
Modem - LT WinModem
Audio - Unknown (ISA device, use default audio drivers and it works as well as I need it to)
HD - Maxtor 6.4 GB (Have also tried a WD 40 GB drive)
CD-ROM - Sony CD-RW 10/12/24 (Rw/W/R)
Was thinking about trying a different IDE cable, right now I'm using a "Cable Select" IDE cable that came with the WD hard drive and read somewhere that that could cause problems as well.
In any case, I appreciate any help that you could give me.
Thank you in advance.
