You might also want to check if there are any firmware updates for the USB3 chipset on your motherboard. lspci should reveal the chipset. My old motherboard had a flaky USB3 chipset (Renesas/NEC) that could only be updated from Windows, so I never bothered with updating it, but there are some that are updatable from within linux or from a DOS boot disk. A bit different topic but similar: I get problems with using a PL2303 usb-to-serial-adapter lately. Same issue on thinkpad and main desktop pc so that might not be the chipset. Something like this: http://www.geekdevs.com/2010/04/solved-unable-to-enumerate-usb-device-disabling-ehci_hcd/ disabling ehci_hcd disabled my keyboard as well so that is no solution ;-) Maybe I didn't fully understand how to do that ... anyone in here already solved that? I use that pl2303 to access embedded PCs like ALIX or WRAP to configure routers/firewalls ... it would be great to have that available on my thinkpad again. Stefan

Re: [gentoo-user] Mac Mini with Grub booting Mac OSX and Windows?!
We can't have more then 4 primary partitions on a hard disk. Gentoo needs 2 partitions, /boot and a Virtual partition (that count's as well as one primary) with all the other folders. Windows will create 2. and Mac OSX minimum 1, am I right?! Your Windows partitions have to be in the first four, but OSX and linux partitions can be anywhere thanks to the gpt partition table. Things are both simpler and more complex than that. The real problem is that while rEFIt/rEFInd, OSX and Linux have no problem dealing with a GPT partition table, Windows only supports MBR. (Windows 7+ supports GPT partition tables but it can only boot from a GPT disk in EFI mode. On a Mac OSes other than OSX must be booted in BIOS emulation mode, therefore the requirement for MBR on the system disk for Windows still stands). GPT and MBR, however, are only indexing schemes: they describe how many partitions are on a disk and their location, but apart from providing a high level 'type' label they have nothing to do with what's inside a partition. GPT-partitioned disks traditionallly have what's called a 'protective MBR', i.e. a dummy MBR which defines a single partition of type 0xEE spanning the whole disk; this is intended to keep partitioning tools that are not GPT-aware from considering the disk uninitialized and inadvertently destroying its contents. However, nothing prevents you from adding to the protective MBR regular entries for some of the partitions, and have the disk look like a 'normal' MBR disk as far as those partitions are concerned. The result is called a 'hybrid MBR' and it's the main trick behind Boot Camp. There is really nothing special about booting (or installing) Windows on a Mac: it just works, as long as you have both a properly set up hybrid MBR with an entry for the Windows partition and a suitable EFI boot manager. The former can be done with a tool such as gpt-fdisk (you can easily find a binary package for OSX, and there are directions for dealing with hybrid MBRs on the author's site); rEFInd is your best option for the latter. The standard Apple boot manager will also do, if you only need to boot OSX and Windows. Booting Linux works in a similar fashion. You don't even need a GPT-aware bootloader: good old GRUB 1 is perfectly up to the task, as long as there is an entry for its boot partition in the hybrid MBR. Then you can load a kernel with GPT support, and from there it's just a standard multiboot setup. HTH, andrea

I had though that the MBR was automatically mapped to the the first 4 gpt partitions because that's they way it's always been on my system. So now I wonder how it's been set that way, because I know i've never touched gpt-fdisk and I didn't use bootcamp. Maybe the refit installer.
