Re: [Soekris] Net6501 location of SATA ports
Robin, The SATA ports are on the corner of the board opposite the corner with the reset button and power connector. In other words, put the board face up in front of you with the power connector facing you. The SATA ports are on the top left corner. They're labelled J1 and J2. For SATA power, you'll need an adapter like that sold with the Soekris HDD mounting kit (http://soekris.com/products/net6501/2-5-sata-hard-drive-mounting-kit-for-the-net6501-std.html). I think my board came with this power adapter, but I could be mistaken. The power connector is a 5 pin connector labelled JP18. It's located along the edge between the SATA ports and the PCIe slot, closest to the SATA ports. -Peter On 5/17/2013 10:22 AM, Robin Kipp wrote: Hello all!

Re: [Soekris] net6501 can't boot with large disk attached
I use 1 TB USB drives and internal 1 TB SATA drives with my net6501. Both work well.

My idle net6501-50 with no fan, standard case, USB boot device, mini-PCIe WiFi, two hard drives, and Linux is at 48C CPU temp right now (ambient 9C). As I understand it, the CPU temperature sensor is relative to a parameter called Tjmax (maximum junction temperature), but the hardware provides no way for software to determine this parameter. The Linux driver requires a special option to set the correct Tjmax (coretemp tjmax=90). I presume OpenBSD needs a similar option. -Peter On 3/19/2013 7:24 PM, David Ruggiero wrote: I've searched and read through the -tech archives and though CPU temps and cooling have been discussed several times, I'm not seeing direct answers to the questions I have.

That seems quite high to me, given that the ambient temp in the room is just 15C (cool basement), and Soren wrote here last year saying to expect about 32C over ambient. So: 15C+32C = about 47C expected. And I'm 20C over that. Yikes,. But perhaps hw.sensors in OpenBSD is buggy for this box and/or a compensation factor is needed to interpret its output?

Must have been a power problem, I guess. BTW, some basic test using dd(1) on those disks' raw devices (running NetBSD/amd64 6.0_BETA2) show read rates of ~ 100 MiB/s and write rates of ~ 20 MiB/s. According to some [1]benchmarks that read rate is what should be expected, but the write rate is suboptimal. The drive's SMART values seem to be ok; I only noticed a fastly increasing load cycle count, and disabling APM rendered it constant but did not increase the write rate. Regarding the HN-M101MBB, I've seen the same problem with the same drives on my net6501. Enabling PUIS (power up in standby) on the drives fixed the issue for me. I'm not sure if the change in boot timing or power demand is the source. Beware: I don't think the net6501 BIOS can boot off drives in standby. I'm booting off USB to Linux, and the OS spins up the SATA drives later. -Peter ___ Soekris-tech mailing list Soekris-tech@lists.soekris.com http://lists.soekris.com/mailman/listinfo/soekris-tech
Re: [Soekris] net6501: Timer problems with Debian, no HPET support detected
Linux depends on an ACPI BIOS to provide configuration for the HPET.
The net6501 does not support ACPI, so Linux does not use the HPET.
However, I've created a patch (attached) for Linux 3.2 that enables HPET
on the net6501. I've been running with this patch for several months
and have no problems.

The system continues running, although I have separately observed some unexplained segfaults, file system corruption (seemingly wiping out the partition table), and one instance of I/O error (a DMA write error to the SATA SSD). Has anybody seen similar problems? Any recommendations? Should I try a different kernel or distribution?

Re: [Soekris] net6501 Dual Wireless Options?
Thanks for the ideas ... one of those options should work for me. I also notice that QCom sells internal USB modules, which I expect I could connect to an internal USB header. -Peter On Oct 6, 2011, at 9:09 AM, Soren Kristensen wrote: Hi Peter, Peter Neubauer wrote: I'm considering a net6501 with two 802.11 interfaces, one with an exterior 2.4 GHz antenna as a bridge to a nearby network and the other with an interior 5 GHz antenna for a local access point.
