Switching back from IDE Compatibility to SATA thru BIOS Setup Utility

I installed XP Pro SP2 on my Y410 by switching to Compatibility Mode in the BIOS.  I'm trying to switch back to SATA Mode but I am unable to do so because the BIOS does not give me that option.

 

Any help would be appreciated.

Re: Switching back from IDE Compatibility to SATA thru BIOS Setup Utility

I'm not familiar on your bios settings but some bios features are not displayed when a certain value is selected. Like I set my IDE to compatipibility but the option below for sata does not display. If I switch to enhanced then the dropdown is displayed. Hope this helps.

Yes, I think your advice will help.  How do you switch to enhanced mode while in the BIOS?  I'm working with the Phoenix TustedCore BIOS.

Re: Switching back from IDE Compatibility to SATA thru BIOS Setup Utility

Hi, is the option you used to change to compatibility mode disabled? I flip the dropdown back to enhanced and a new dropdown below will be displayed. I didn't get a chance to look at it last night but will try tonight if I can. BTW I'm not too familiar with the Y410 bios but I think most of the dropdown are the same with the Y310. Also I tried doing that but it ended up in a BSOD on my machine and I can never recover from that until i changed it back to compatibility mode. So my solution is to do a fresh install using the enhancemode with the drivers already included in the cd so that the hdd will be detected.

Re: Switching back from IDE Compatibility to SATA thru BIOS Setup Utility

My BIOS Setup Utility doesn't even show the compatibility mode option.  I called Lenovo tech support and they told me that I should try updating the BIOS.  I updated the BIOS by downloading the available update off Lenovo's site but the BIOS Setup Utility did not seem to change.  No new drop downs/options appeared.   Tech support told me there's nothing I can do.  This is frustrating!  How is it possible to be in compatibility mode without being able to configure compatibility or SATA mode thru the BIOS?

You'd use nLite to integrate chipset drivers in your XP disk.

 

Download chipset drivers (Intel or Lenovo - no difference), run their install and when the install window shows press Win+R, type %temp% and search for folder that contains unpacked chipset drivers. Copy this folder to another location.

 

Download nLite, copy all files from your XP installation CD to some folder and then follow instructions of nLite.

 

Voila.

Re: Switching back from IDE Compatibility to SATA thru BIOS Setup Utility

This does not address the issue with lacking the ability to switch back between "compatibility" mode in the bios.  You will need to resolve that via an update or which ever means you find effective. 

 

However, after you get that taken care of you do not need to reinstall your OS if u get the BSOD from lacking sata drivers.  If you load win in compatibility mode it will run with out any sata drivers.  Is the performance drastically effected?  not sure.  There is usually no reason to keep a sata drive running in compat mode though, that is more for diag or legacy type systems or older IDE drives.  If you find that you installed xp for example in compat mode then you will need to download your sata drivers and install them then reboot your system.  When you reboot you will need to switch your mode back to "AHCI" or you will get the BSOD.  I just wanted to make sure you know you dont have to reload your system if you have this problem.  Just update the drivers and then change the mode in the bios to "AHCI" then your good to go.  I did this on a test machine just to verify before posting. 

 

The moral of this story is "dont load your os in compatiblity mode".  Just get your drivers when you do your initial install of xp or use nlite as suggested. 

 

The following is straight out of the support doc for the sata drivers:

NOTES

A Blue Screen error will come up on the Windows preload when these models boot
with "Compatible" mode instead of "AHCI" that is modified from the BIOS Setup/
Config/Serial SATA menu. This is caused by an absence of a compatible driver
on the Windows preload. Stay "AHCI" mode when you boot Windows preload.

Re: Switching back from IDE Compatibility to SATA thru BIOS Setup Utility

Here is some more info I took from another forum.  Please note this is not my own but may help clarify some of the questions earlier in this thread.  Most of this is relevant to this thread.

 

"The chief advantages of compatibility mode is you can use the drive with operating systems that do not recognize SATA drives (Win98, ME, etc.), you can use disk utilities that access the drive with standard PATA commands;  and (as you noted) you don't have to bother with SATA drivers in any OS.   This mode makes NO difference in the access times or sustained transfer rates of the drive => the head still moves at the same speed; and the rotational speed of the drive is still the same !   It MAY slightly slow buffer -> main memory transfers (from SATA rates to 133MHz IDE rates); but I'm not even sure it does that (since the same "pipe" is still being used => the SATA cable).   About the only NOTICEABLE difference is probably that when you look at the drive in Device Manager it will show as IDE rather than SATA."
