The usual case is that if the motherboard has UEFI boot firmware, that is the only firmware available, no company will perform twice the work to support UEFI and also legacy BIOS for the same motherboard. UEFI does have a legacy mode in which it can behave like legacy BIOS for booting operating systems which have no UEFI bootloader capability, like DOS or very old versions of Windows. Perhaps what you really want to know is whether secure boot can be disabled (cryptographic verification of bootloader files). Disabling secure boot is very likely a configuration option. Perhaps the vendor has a manual available online to confirm, but the phrase you should look for is disable secure boot, not disable UEFI. -- Chris Caudle

I have worked with an Intel motherboard which used the Intel sourced UEFI, and it could act as a legacy BIOS, but was really booting UEFI to configure the processors, then effectively loading a program that behaved as legacy BIOS, so to a bootloader it appeared as a legacy BIOS but was in reality a hybrid system. -- Chris Caudle

Hi, this is my current decision, but I'm still missing some information, that I might get on Monday. CPU https://www.reichelt.de/PC-Components/CELERON-G1840/3/index.html?&ACTIO… I suspect for CRTs frequencies > 60Hz are still possible? Mobo https://www.reichelt.de/PC-Components/GA-B85M-D3H/3/index.html?&ACTION=… DualBIOS unfortunately has nothing to do with disabling UEFI/Secure boot. "GIGABYTE UEFI DualBIOS™ GIGABYTE motherboards feature GIGABYTE DualBIOS™, an exclusive technology from GIGABYTE that protects arguably one of your PC's most crucial components, the BIOS. GIGABYTE DualBIOS™ means that your motherboard has both a 'Main BIOS' and a 'Backup BIOS', making users protected from BIOS failure due to virus attack, hardware malfunction, improper OC settings or power failure during the update process." Linux compatibility isn't verified, I still have to do it. This RAM https://www.reichelt.de/DDR3-RAM/BLS4G3D1609DS1S0/3/index.html?&ACTION=… or this https://www.reichelt.de/DDR3-RAM/KVR16N11S8-4/3/index.html?&ACTION=3&am… or that one https://www.reichelt.de/DDR3-RAM/KVR16N11S8H-4/3/index.html?&ACTION=3&a… Regards, Ralf

The legacy modes should boot your present drive. There also look to be a number of "performance" and "power saving" features you may wish to turn off :) The CPU and the board both seem to handle up to 3 displays (most do). Any one else have one? The CPU should be fine, it looks about like what my son has (running Kubuntu). I can't help with ram I just picked "some" (8G) and put it in. Two matched are supposed to be faster as the access can be interleaved, but I just got a single and it has been "fine" (wonderful word). I have 4 terminals, 2 pdf readers, geany, FF with three pages (close to 40 total) of tabs open and ardour running with a 17 track session. My system says I am using 1.6G of 7.5G ram (I guess the 7.5 excludes memory not belonging to my user) There are various other utilities running too. Swap says 0bytes. (the way I like it :) swappiness is 10 by default in UbuntuStudio which seems to work much better than the default 60. All that to say, I think 4G ram would have been enough for most things. -- Len Ovens www.ovenwerks.net

Hi, I cleared the CMOS RAM of the "broken" mobo, removed the RME and TerraTec sound cards and unplugged the DVDRAM from the PSU and mobo, now everything works, I just needed to rewrite a script to use enp2s0 instead of enp3s0. After just clearing the CMOS RAM, without removing hardware, I got back the start beep, that was missing before, but there was no monitor signal. Perhaps I was impatient and didn't wait long enough and removing the devices wasn't needed. Anyway, after booting worked without the devices I mounted the RME sound card, but not the TerraTec sound cards and reconnected the DVDRAM, enp2s0 became enp3s0, my script now gets the device name by $(basename $(ls -d /sys/class/net/enp?s0)) ;). Excepted of shielding issues for the RME card, especially when loading a YouTube video there's nice parasitic noise, everything still is fine. The parasitic noise seems to be a little bit louder now, but the fans seems to be more silent then before. The only problem is, that the start from BIOS to GRUB is slow, but not dramatically slow, startup from GRUB to Linux still is quick, but I didn't restore all old BIOS settings, perhaps that does cause the slowness. Today I can't continue trouble shooting. I still want to buy a new mobo, but assumed the issue with the old mobo is fixed, then I wont order a new mobo this year. iPad browsers and the iPad MUA are a PITA, nice to have the Linux PC back at the moment.

(I think the Xeon D is meant to replace the Atom userver CPUs) Also note that the ones that say "up to 3.* Ghz" are showing the top Boost speed, not the running speed. (the i7) Yes there are some CPUs with no GPU, but they are either BGA for embedded apps, or high end. Unusable on most MB or too expensive. The other thing is that deselecting hyperthreading, leaves only the slowest things around. For example, the xeon E3 at 3ghz which is about the same as my i5(a)3.2ghz with Graphics... meant for low power uses. The xeon E5 with 6 cores only runs at 1.9Ghz... also a low power version. When I was looking into this stuff, I found that the MB that can handle even the low end xeon (where the CPU price was close to the i5) was almost double the price. So yes, there are no-GPU CPUs around, but they are not very useful. Thanks for the link though, I might keep that around. -- Len Ovens www.ovenwerks.net

I did, and the complete FX line (unless called APU) does not have integrated graphics up to my knowledge. And AM3+ ist pretty common, nothing high end or "server" here, probably the most common socket you get for AMD. If I'm not mistaken, none of these have onchip graphics: http://www.amd.com/en-us/products/processors/desktop/fx Quite a few to choose from, if you ask me, but I haven't checked each one in detail. And wether they suit you or not for other reasons is of course up to you. I have no intention to sell you a brand or specific model, I was just trying to help getting a general overview. C'est tout.

On Fri, 18 Dec 2015, Ralf Mardorf wrote: Personally, I feel the i5 quad core is the intel of choice (even if you can afford the i7 quad core). The i5 quad core is FCLGA1151 socket. The i3 dual core and pentium dual core use the same socket, so upgrade is possible. The Celeron does not and so would not be upgradable. The intel graphics with this cpus seems to be well supported in Linux and does not interfere with RT operation. I would recommend some of the Atom based boards for audio if it were not for the graphics GPU they come with (closed - poor linux support) and the general lack of expansion slots. Looking at the MB I did choose... It seems a last generation i5 has the same socket as some of the celeron products. (1150) The Harrison top of the line consoles use AMD optron (I think) CPU's... but they do not use graphics cards with their DSP CPUs and the Optron is not the cheap end. Other than that I have no experience with them. I do not know how they are with latency handling. One of the technologies they use to improve throughput involves over speeding one core if the others are idle (cool). This will not help low latency performance (rather the opposite) but This may not be a problem in Performance mode anyway. The comments so far have been about this or that being "fine" but have not included what audio hw or latencies used at. 64/2 is concidered by many people to be fine and lower is not attempted. USB AIs should all work down to that latency. However, PCI(e) cards should have no problem running at 16/2. This is in general MB design. moment I'm in favor of an Intel Celeron Dual-Core G1840, 2x 2.8 GHz, 54 W, generation Haswell, SSE 4.x, assumed more cores shouldn't gain much for audio and MIDI usage. (at the moment): I have been very happy with my ASUS Z87-K (haswell chipset) It was chosen from a long list of ASUS boards and falls below the middle in price. It has two PS2 sockets (mouse and KB) and three PCI slots of which only one wants to share IRQs (I don't use it). It has 4 PCIe slots as well. It does not have builtin bits and pieces that the more costly boards have, which I concider a plus (I am happy to pay less for a better board). It will boot ans install non-UFI partitions. I have no problem running it for days at 16/2 with no xruns provided things like cron are not running. (UbuntuStudio distro) The AI being an older D66 and the second card an AudioPCI (ES1370) which is also used for MIDI. Dispite some of the opinions in the list, I would still choose PCI based audio/MIDI over USB for timing sensitive use. (making notes play or timecode movement) I am not so picky for use with a control surface to control a DAW though. I would also look at the MSI B85-G41 which has two PCI slots. (the z97 would probably work too but costs more) Remember that while the eco sounds like a nice idea (TUV), It likely means bad things for lowlatency audio... disk being spun down, quick to go to sleep, etc. which you are going to disable anyway. Remember that a class D amplifier uses much less power than a class A tube amplifier, but the tube amplifier still has "that sound" and guitarists still record with them regardless of power used. The MSI B85M (1 PCI) would be better. This one says "GIGABYTE UEFI DualBIOS" That sounds promising. One out 5 reviews says the PCI slots were dead using cards that work in other systems. Concidering that the chances of at least some of the other users did not even use PCI slots that is trouble some. Also a number of DOA boards. Also look at the GIGABYTE GA-B85M-D3H which seems to have better reviews. These likely are to do with robustness rather than suitability to audio processing. Still good, but audio processing first. Remember that the standard all advertising is based on is throughput which is often anti-lowlatency. I would concider TUV a liability for audio use. -- Len Ovens www.ovenwerks.net
