How to access caching ssd

Hello, colleagues!

Are the owner of laptop Fujitsu S782 (http://www.fujitsu.com/ru/products/computing/pc/notebooks-tablets/advanced/lifebook-s782/index.html). On the characteristics in addition to the main HDD (which I already replaced with SSD) there is another (excerpt from website):
mSATA, 32 GB, the Cache memory based on solid-state drive to implement technology IRST and Express Cache

In the BIOS the drive is not detected, but the disks are listed like this:
* DRIVE0
* DRIVE2
* DRIVE3
* DRIVE4
See, that missed DRIVE1

When I install Ubuntu, the drive is detected (sdb), but was tormented by the question: how to specify in the BIOS to start with it? I want the media to use as "/", and the second SSD as a "home".

Thank you!

honestly, how in the BIOS to specify — don't know.
but your scheme you implement is not obstructed. put grub on the disk, which is seen, and it also make the /boot partition and pass options to the kernel that root is on sdb.
Although the root of the 32Gb I would not put. /var I'd also made on a larger drive.

in the case of Ubuntu that's all you can do it from the installer.
The main thing — at the end of installation when it will ask you "where to put the bootloader" — select the correct disk (in your case probably sda)

P. S. it is important that these caching features were not strictly implemented at the level of BIOS, in this case the machine will not care what and how you spaced, it will be on that disk writing cache... take a closer look at the BIOS settings on the subject of this moment.

This solution suggests immediately, but I'm not sure about /var. Although if you swap a place on the same drive, then Yes, it is better to move :-)

This media is used by Windows (in supply) as the storage file hybernate, so I don't think that in the BIOS something serious too clever by half. Of course it would be necessary to disassemble the laptop and look on circuit design, which connector is used, can be, if you perekinuty plumes, all self-saboya will improve. But what I don't want to play LEGO :-) - Etha63 commented on October 3rd 19 at 04:02

it is not necessary to disassemble a new laptop :)
if it works, what it once again to touch.
following the logic — after peretekaniya plume you have your new ssd will be invisible.
I think in the BIOS specially made Kostelic to the "normal" users it was not possible to install the system on disk, which the manufacturer is positioned as a cache.
PS by the way, Yes. you can also just put the boot loader on the new disk. and the entire system with root and bout to post on this embedded.
but still 32 gig under all system logs and blackjack are damn few :)
32 little, at least under vendu.

I have also K46CM SSD was walked in disguise.

Miraculously, after several preinstallato Axis (for other reasons don't like it...), the SSD suddenly shone in the Explorer.
Unfortunately I can not explain... o_0.

Although nothing from him. Huch, I will have to change it to something under 500 hectares, that is... - Etha63 commented on October 3rd 19 at 04:04
