the last BIOS is still 205 for JH.

select your model in the ASUS download center, it should point you to the correct files.

The G750JH comes in 2 revisions so far, the JH version and the JHA version, with 2 different numberings in BIOS names. If you can't install the JHA version, then install the JH version, highest number at the time you are reading this...

Here are the versions available as I write this:

31817

I have the JHA, so I have the JHA 203 bios installed.

31819

Any idea what the difference is between JH and JHA ? There's also a JXA, btw. But no "JWA" is listed, when you choose this model in the Asus download system and check the BIOS upgrades.

Before I received the JHA I thought it might be the new stepping of the Southbridge controller with the USB fix, according to internet lore the buggy Stepping C1 is Revision 4, and the Fixed Stepping C2 is Revision 6. My JW/JX were both Stepping C1 Revision 04 - and as it turns out, so is the JHA:

31827

31828

Anyone else know?

Perhaps the JHA/JXA's had the vertical lines removed...? ;)

My JH has a BluRay and a SSD (plus a mechanical hard-drive), yours too ? (I know there are models with DVD-drives and without SSD)

Pierre990429, yes to both - the -DB71 model is similar across regions, varying in amount of memory (24GB), the size and config of SSD (2x128GB RAID0), and a BD-RW or BD-R Combo. The wifi/bt varies too - Killer 1202 802.11n + BT.

The JHA -DB-71 seems to have the exact same options as the JH here.

IDK if there are JHA's that didn't come with Assassin's Creed, but this one did. Is the JH*A* for Assassin's Creed? Seems odd to that it would have a separate BIOS just cause it came with a bundled game :)

Oh yes, I didn't think of that ! "A" for Assassin's Creed.
1st game to have a BIOS protection ? (just kidding)

Someone mentioned to me that the G750JH(A) bios is for the Raid 0 model, but I don't have this unit to verify if somebody else can.

I only have the G750JW which has the options for AHCI, RAID, and IDE under the 'Advanced'/SATA Mode Selection, so curious if the G750JX (don't have it either) and G750JH have different options in the bios, or there is some other difference.

Anyway, whatever the case it sounds like it's probably a good thing that Easy Flash and Winflash don't let you flash the wrong model bios.

If anybody is interested, hit the 'F12' key in the main menu of the bios to see which bios model you have which you can also confirm in Easy Flash and Winflash as well when you try to load the new bios version.

There are two BIOS for the G750JH - BIOS 205 (G750JH) - BIOS 203 (G750JHA) both are dated 9/22/13.

BIOS 205 is for G750JH that uses AHCI (1-256GB SSD & 1 HDD).

BOIS 203 is for G70JHA that have 2-128GB mSATA SSD configured RAID0 & 1 HDD. Only BIOS 203 (G750JHA) work for me as I have a G750JH-DB71 configured RAID0.

If you only have 2 hard drives you need BIOS 205 (G750JH).

I guess that makes sense, the RAID software needs to be built into the BIOS to support the Windows RAID software, but I think others have done RAID between their 2 bays with their non "A" laptops.

I suppose I could ask Asus directly - I wonder why the don't add some supporting text to each BIOS type to let us know what the difference is between the JH and JHA?
