Hi joe_intel,
Thank you for your reply. Unfortunately it's of no help / not applicable to me, for the following reasons:
- there was no Accelerate button/tab in the IRST GUI, ever (which is why the cache never worked, I guess). But the GUI did show the SSD and I did set it to "Available"
- the OS was certainly not installed in RAID mode - the RAID only appeared with my installation of IRST, i.e. IRST set up the RAID after years of that machine's running in IDE
- Ctrl-I during POST does nothing: no RAID BIOS or RAID option ROM appears, the boot happily starts Windows without stopping.
In short: IRST installed a useless RAID on my machine, probably because the machine's chipset doesn't support it. I think that the IRST installer should have detected the condition and simply not install at all - but in any case, I want to get rid of it now, and I'd find it inconceivable that the only way of getting rid of it would be a complete reinstall of the OS from scratch?? That would really be reckless on part of IRST.
Here is what Device Manager reports:
- could you suggest any other way of dropping the RAID and revert to IDE? Like "Uninstall the driver", maybe??
Many thanks for your help!
