Description of problem:
Using RH 7.2 with Sony DVD-ROM DDU1621. I was successfully install
RH 7.2 using boot disk + CDROM on that DVD Drive.
When i try to mount CDROM on that DVD drive , there are error
telling that "invalid block devide". After investigating,
It seem like linux kernel assumed it as "ide-floppy"
(the ide-floppy 0.9.x error msg appear during dmesg)
The RH 7.2 linux kernel compiled with CONFIG_BLK_DEV_IDEFLOPPY=Y.
when i recompiled as '=m', the kernel treat it as DVDROM drive.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.plug Sony DVD Drive DDU1621
2. boot with kernel 2.4.7 with CONFIG_BLK_DEV_IDEFLOPPY=Y
3.mount cdrom or dvd-rom
Actual Results: cant mount cdrom
Expected Results: can mount cdrom.

dmesg when the config_ideflopy=m
Hmmm one quick question: does it help if you type "depmod -ae" as root ?
erk, Sorry. Its Working... it's a dupe?
[root@localhost RedHat]# cat /proc/ide/drivers
ide-cdrom version 4.59
ide-floppy version 0.97
ide-disk version 1.10
but why when CONFIG_BLK_DEV_IDEFLOPPY=m , i didnot require to depmod -ae ?
(or i did it automaticcaly during make modeul_install?)
