Hi everyone.
I've been happy with my SR-2 for quite a while until recently when it started to screw up boot settings for god knows what reason.
All CMOS settings (e.g. overclocking, time) stay the same all the time, so it's not a battery issue for sure. It just rebuilds the drive list at random times. My boot SSD always ends up the last for it is connected to Marvell's SATA3 controller, even USB drive gets a higher position on the list. The mobo won't skip the unbootable drives (all partitions except the one with Windows are set inactive) until it sees a drive with an OS, and I'm always getting a blinking cursor screen with nothing happening until I reboot and either fix the boot settings manually or use Boot Selection Pop-up.
I tried cutting the boot order list down to just one drive. Sometimes the mobo keeps this setting but after this crap happens again, my fisrt SATA2 HDD replaces my bootable SSD in this menu, and that's it.
I've noticed that it rebuilds the drive list each time a USB storage device is connected. I have two active (powered) USB hubs daisy-chained, one of them is on a 5,5 m cable. The problems started circa the same time I've made this USB chain. Perhaps, the connection is lost on power cycle, and it triggers the drive list update and reset. Even if this is the cause, I don't see why it won't just skip through all the drives until it sees an active partition.
BIOS v.080016 04/24/2013 Maybe there's a way to make sort of smart move and place an OS loader to other drives that would point to my SSD? Like as if you had a dual-boot with linux, and it would boot Windows from a certain drive by default.
Maybe I should do something to HDD's mbr/partition/whatever so the mobo would skip through?
Or any other advice? Please, help.
UPD: OK, I've traced the problem to one of the HDDs that wouldn't skip. I've purged the boot info of the mbr with MBRTool, but to no avail.
