Re: [issue1127] cdrom drive not detected

I have a similar error on my home "debranded HP media PC" which is a Core2Duo intel chipset based motherboard, SATA hard disk and DVDRW, with bios option set to AHCI mode instead of IDE mode. With default boot options (no keyboard input) the CD fails to boot with same rootvp can't be found, apparently trying acd0, which doesn't exist under AHCI, and ends debugger prompt. If I watch the boot process and choose the "no AHCI" boot option, It finds the DVD rom and works fine, presumably because acd0 exists under nata. On a slightly older version, It would fail to the mountroot prompt and typing in cd9660:cd0 works sometimes or not with an "Device is in process of getting ready" type of message, showing up...

I receive the following error when attempting to boot the CDROM iso:

iso_mountroot: can't find rootvp

This error sends the boot process into the debugger. Actually, I've had this
problem with the last several versions of DragonFly BSD. Apparently, this
problem is significant as others have experienced it also.
