HI, Still waiting for response, putting some more information for your better understanding. Exact error: in dmesg scsi 4:0:0:0: Direct-Access Dell Virtual Floppy 123 PQ: 0 ANSI: 0 CCS scsi 3:0:0:0: CD-ROM Dell Virtual CDROM 123 PQ: 0 ANSI: 0 CCS
If you see this, then the kernel knows about your CD-ROM device. This is not a kernel issue.
sd 4:0:0:0: [sdc] Attached SCSI removable disk "ISOFS: Unable to identify CD-ROM format"
That's pretty obvious. The CD isn't burned correctly.
Btw, I can mount ISO image successfully (i.e mount -t iso9660 -o lo /path/to/image /mount/point), So i am sure FS is well supported.
It is. This is not a kernel or FS issue, it's a media problem. The CD you're feeding your machine is NOT an ISO9660 CD. The ISO image is
fine since you can mount it via loopback, but the CD itself is burned incorrectly.
Attaching my config files as. LSPCI.txt :-> output of LSPCI command image-kernel-smpx86.conf:-> Kernel config paramater Bootfloppy-kernelXX.conf:->Boot image kernel config I have compiled the kernel to support cd-rom with my best linux knowledge, but unfortunately it's not working for me. I am quit sure that my kernel have all the required option enabled , it seems to me as kernel bug. You comment/suggestion is needed. Plz help.

After successful compilation and installation with new kernel, :- --System is not able to mount cdrom. --Always generate error, "medium not found" --dmesg have an entry some thing like " unable to understand cdrom format" I don't know what went wrong, but i cross checked my new kernel config and my new kernel have following support:- (in respect of cdrom) --SCSI device drive support [*] --iso9660 file system support [*] --ata-ide device support [*] I am attaching my kernel.conf file as attachment for better understanding. let me know if some other information is need in order to understand my issue. Also, I am highly confused in selection of modules as static or dynamic. It will be great help if any one can suggest me the rule/law behind dynamic[M] and static[*] selection of kernel modules. *I just need to ask , what if i select all kernel modules as lodable modules [M] instead of static modules [*] or vice versa !!
