So you are booting from the disks in these optical drives. So the only thing that can be used is the storage Option ROMs in the BIOS. But since it is either AHCI or IDE mode, there isn't a storage Option ROM that can be used. Also, we are talking a true legacy BIOS firmware, just a 16Kbit BIOS chip, on a board and chipset that supports IDE drives. Will a BluRay (BD) drive work without a driver or Option ROM, on a SATA port that is shared with and IDE interface? I would not depend on it. |

Why would other drivers improve the situation? The drivers are not being loaded at all, since Windows doesn't even get started...
My drives are Pioneer BDR-S09XLT and LiteOn iHAS324.
Hm yeah, interesting thought |

I'm at a loss about what to tell you. I've never had a situation like this with optical drives.
What SATA driver are you using for the Intel SATA controller? That will be shown in Device Manager, either under IDE ATA/ATAPI controllers, or Storage Controllers. I'm wondering if the Intel AHCI driver would improve the situation. The P55 chipset is from the first series of single chipset/CPU "PCH" platforms released by Intel, what we would now call the 5 series chipsets. I was looking through the Intel datasheet for the 5 series chipset, and found some interesting information, although how that directly translates to your situation or finding a fix for it is not clear. The information is really is more of an explanation about how it operates, which may be related to your results. For example, three pages out of the datasheet:    Link to the full datasheet: http://www.intel.com/content/www/us/en/chipsets/5-chipset-3400-chipset-datasheet.html After reading some of this, you may understand why the ordering might make a difference. This is a good example of what happens when multiple storage protocols (SATA and IDE) are combined together into one logical interface as the user sees it. Things are not as separate and independent of each other as we would assume they would be. It seems to me after going over just what I posted above, there must be more to configuring and using the SATA and IDE interfaces on your board and BIOS than I am aware of. I also don't see any reason for the idea there will be other unpredictable results when using standard HDDs in any order. What are the two models of optical drives you are using? We are currently in a similar situation with SATA and NVMe, which is also confusing. |

Then your stuck with one of your working options,...or attach it to the Marvell controller.

Yes I've tried a Bluray Drive from a different company also -- same results.

What you may be encountering is a DVD drive that does not adhere strictly to SATA spec ,...from what you describe in IDE mode. Have you tried a different DVD drive?

No. When I set my SATA configuration to AHCI mode (my default config), then I can apparently only boot from the DVD drive when it's connencted in a special order.
When I set it to IDE, any order works. I normally use Load Performance Setup AHCI Mode - it simply loads AHCI mode plus some additional unrelated options elsewhere (CPU behaviour, HPET-table etc). No I'd rather not connect anything to the Marvell port since it is unfortunately utter crap.
Well.. the problem is unpredictible behaviour. In the beginning I didn't even know what was going on; I thought it's an issue with my DVD image. I burned a few disks again but nothing worked. I had no idea what was the cause, until I played around with the SATA cable order. Now imagine I reorder the drives so that booting from CDROM will work.. what else will happen? Will the HDD show buggy behaviour instead? I have no idea, so I want to have sorted out, what this bug is and where it comes from.
I am fully aware of this. Edited by nuc - 02 Apr 2016 at 10:46am |

I'm confused now, in the post above you now say that you cannot boot
from any optical media/drive (??) after changing the SATA mode, but in
your first post you could boot from the optical drive if it was first or
second in the SATA port order.
So you now cannot boot from any optical drive, which you could do so before changing the SATA mode? One thing I did not mention, which is also stated in your board's manual, is it is not recommended to change between any of the SATA modes once the OS has been installed. Such as, changing from AHCI to IDE mode. That is due to the way Windows deals with storage drivers. IDE, AHCI, and RAID modes all use different drivers, although the Intel SATA AHCI and RAID drivers use the same installation package. Changing the SATA mode from AHCI to IDE or vice versa just in the BIOS does not affect the OS installation. When you boot the OS after changing the SATA mode, that is when you can have problems. That seems to be the case now? I forgot to ask this previously, but what is the problem with connecting the DVD drive in a specific order or SATA port that works for you, rather than another order that does not work? I can't find anything in the manual that accounts for the apparent ordering, but I don't have your board and BIOS to experiment with myself. I wonder if the ordering of the drives that you apparently require is related to this statement in the manual: If you select [IDE] mode, the options ?�SATAII 1,2,3,4 Configuration??and SATAII 5,6 Configuration??will appear. This seems to indicate a grouping of the SATA II ports into two groups, which can be configured in some way independently. The IDE Configuration section of the manual is confusing me. Do those options appear when the SATA mode is set to IDE? Do those options apply to the SATA ports, or just the single IDE connector, that may be connected to two drives? Note in the IDE configuration options, the Type of drive ([CD/DVD], [ARMD], [Auto], etc) is an option that needs to be selected. I'm wondering if the selection of the drive Type in IDE mode somehow affects the SATA mode. I asked about some options in the Exit screen, the Load Performance Setup Default (IDE/SATA), and Load Performance Setup AHCI Mode. But no comment about those from you. Any idea what they even do? While this is not always recommended, did you try the Marvell SATA ports for the optical drives? Not having your board and its BIOS to work with is a significant limitation for me in attempting to diagnose your situation. I'm not sure what your current situation is, but is seems you've gone from the optical drive working in some configurations to not working at all. Please clarify this for us... |

Hi parsec!
First of all thanks for your interest and your fast and versatile response! :)
It's SATA only, connected to the native Intel SATA2 ports.
nope
The latest BIOS v1.70
I tried doing so now - it didn't make any difference.
Yes, everything is working correctly apart from that.
Big thanks for suggesting this! My standard setting is AHCI Mode, so I tried out IDE Mode and *surprise* suddenly booting up from the DVD-Drive works fine! Whenever I set it back to AHCI any optical media refuses to boot (I tried disabling some AHCI specific options too, but it didnt help). So it seems that this bug is caused by the Intel AHCI module inside the BIOS ROM. Any suggestions from your side? Thank you so much :) Edited by nuc - 29 Mar 2016 at 8:22pm |
