Description john 1999-05-23 03:45:46 UTC
/dev/cdrom was mapped to /dev/hdb on my fresh install of
RedHat 6.0 instead of /dev/hdc as it really is. This is not
a fatal flaw, just an annoying one, which I corrected
/dev/hdb is another IDE hard disk drive in my system. All
drives (fixed and removeable) are running off the on-board
IDE controller of my motherboard.

How are your jumpers set for these devices?

What brand and model of motherboard are you using? I have not seen
this behavior and it seems your controller chipset is doing strange

Comment 3 Michael K. Johnson 1999-07-29 21:35:59 UTC
This really sounds like a chipset bug.  I'm resolving it as
"WONTFIX", but if we get enough other reports to figure out
what is going wrong we can change that.

You might want to send the output from dmesg showing the IDE and
disk detection phase:  As a sample to show you the part to send:

VP_IDE: IDE controller on PCI bus 00 dev 39
VP_IDE: not 100% native mode: will probe irqs later
    ide0: BM-DMA at 0xd000-0xd007, BIOS settings: hda:DMA, hdb:DMA
    ide1: BM-DMA at 0xd008-0xd00f, BIOS settings: hdc:DMA, hdd:DMA
ide0 at 0x1f0-0x1f7,0x3f6 on irq 14
hda: ATAPI 32X CD-ROM drive, 256kB Cache
Uniform CDROM driver Revision: 2.54
