error messages in log file - how serious are they?

[Elton Woo]

I get error messages in my boot.log file:

COMMENTS: There are no disks in the drives. /dev/hdb is my LS-120
diskette drive, /dev/hdc is my cdwriter, and /dev/hdd is my DVD reader.
Also, I do have sound. (Ensoniq 64). 

QUESTONS:
(1) How concerned should I be about these error messages?
(2) Should I open a bug report, and if so under which component?

TIA,

Elton ;-)
