I can confirm (as others have) that this modded bios works.

Y580 with windows seven, had bios version 2.07.

Had to change RESSDIN TO RESSEN on line three of platform.ini file to get it to work (as OP has informed us).

Thanks slv7!

Flashing with modded 2.07 ROM yields:

IHISI: Flash write error in SMI!

SMI: Return Code 0x25

Laptop is locked and fan is on full blast. Will need to disengage the battery to reboot it.

Been at this for a while, so I've generated the new v801Fix.rom bios and I'm still getting this:

EC filesize input error

Any takers?

Any reports to successful downflashing?

You are wrong ssd become hidden when srt is active on your system and make an opposite what u think.

hybrid drive does not give you more performance than ssd+hdd alone its almost same performance with glitches.

In real SRT works as software layer.

Intel products have predetermined support cycle(from currents os to next one) and intel doesn't give us updated software anymore.

eg. why not release updated srt drivers for its legacy products. Intel is too greedy $$$.

If u install your windows system on ssd and want srt the same time = srt worthless u dont get sinificant performance.

the best is seperate disks with system on ssd and hdd for data storage.

i quote from andatech article:

AnandTech - Intel Z68 Chipset & Smart Response Technology (SSD Caching) Review

in short:

"SRT won't work in AHCI or IDE modes."

Enhanced mode is the most secure, but it limits the overall performance.

In enhanced mode, if you disconnect your SSD cache or the SSD dies, your system will continue to function normally.

Maximized mode offers the greatest performance benefit, however it also comes at the greatest risk.

Maximized mode:

Cacheable writes just have to hit the SSD before being considered serviced. Intel then conservatively writes that data back to the hard drive later on.

Enhanced mode makes the SSD cache behave as a write through cache, where every write must hit both the SSD cache and hard drive before moving on. Whereas in maximized mode the SSD cache behaves more like a write back cache, where writes hit the SSD and are eventually written back to the hard drive but not immediately.

It doesn't combine the SSD and the HDD into one volume. The SSD simply becomes a transparent cache.

If I understand it correctly, SRT works by using your SSD of choice as a cache. It does not combine your HDD and SDD into a single volume like Lenovo's cache system.

This makes it more redundant in case of SSD failure/removal.

Hi,

I'm looking for a BIOS that would make it possible to enable Intel RST caching on Y580.

Does such a BIOS even exist? did any of you made such setup work?

This is a question that seeks a conclusive answer.

All I've seen thus far has been enabling overclocking the GPU.

Tried flashing from windows 7 and got this:

IHISI: Flash write error in SMI!

SMI Return Code: 0x25

Here's another problem if flashing from Windows causes an error. The laptop will not shut down and will have to be unplugged and have its battery removed.

RTFM then

I actually don't have pictures of ALL the available settings, I've only seen the pics which are in the link above, but I really think that what you're looking for should be available.

Much obliged and gladly received, svl7.

Is there a readme somewhere with a list of the enabled vs listed features?

In case this was missed and I will heartily take RTFM at this point, what features have been unlocked on the Y580 and what have been confirmed to work?

I am simply looking to enable the RAID function so I can make use of Intel RST. The software solutions out there are a tad wonky.
