Hello there! Long time no see 8)
Intel® Rapid Storage Technology Driver is available for download - TRIM function for SSD drives is enabled now.

All what i can say now, after upgrading to latest BIOS and Win7, i'm still missing a lot of useful features in BIOS. Like ability to save more than one custom settings for example. And cooler fan speed control would be great... And more detailed info on some undocumented features. And more, and more, and more... IDCC is sucks.
It's looks like we will recieve new BIOS only in case of EXTREME bug in chipset 8(
Anyway Bonetrail is solid as rock at defaults, so this is enough for me.
