naw my boards pretty new. its an intel with onboard NIC and a P4. the bios settings are fine ( ithink) wheni realized i had these problems i tried setting the drive detection manually but the problem persisted, now i have it on auto. also i just rebooted now and took a look through the bios settings and i didnt really see anything that would make a difference, however if someone knows anything i may have over looked, please let me know! i noticed this, which i dont really understand, my system emulates scsi for ide atapi cdroms?
<6>scsi0 : SCSI host adapter emulation for IDE ATAPI devices
<4> Vendor: PLEXTOR Model: CD-R PX-W1210A Rev: 1.04
<4> Type: CD-ROM ANSI SCSI revision: 02
<4> Vendor: ATAPI Model: CD-ROM SPEED-8X Rev: 8.3D
<4> Type: CD-ROM ANSI SCSI revision: 02

this might just be something i never knew about and is completly normal. however i see no reason why ide devices would be scsi emulated? maybe there is something i am missing. those are the right attributes of my drives. that entry is from /var/log/boot.msg
here is /var/log/warn
