Install Debian Stretch 10 on HPE Microserver GEN10 | Update

microserver, amd, opteron, x3216 x3418 x3421

Pure DEBIAN :)#

The HPE Microserver GEN10 is an impressive piece of rock-solid hardware. Of course… ILO is missing compared to GEN8 but for most use-cases thats not a real issue.

Debian buster runs nearly out-of-the-box using the netinstall image via USB Stick or network boot. The following tweaks are required to run it flawlessly:

No Graphics after running the installer#

The firmware package firmware-linux-nonfree is required for the AMD APU. Adding “nomodeset” to kernel command line may also work as mentioned on debian.org

IOMMU Error#

You may notice a iommu error on boot: the iommu is disabled by default – to enable it add the following parameters to your grub config:

File: /etc/default/grub

GRUB_CMDLINE_LINUX="amd_iommo=on iommu=pt"

Run update-grub2 to apply the changes and reboot the system – press F2 within the boot menu and to open the BIOS/UEFI menu. The iommu has to be enabled in Chipset -> GFX Configuration -> IOMMU.

In case you didn’t run any VMs on the maschine consider to keep iommu disabled – otherwise the SATA ports (Marvell 88SE9230) on the front become unusable!

Netgear GS108Ev3 Firmware Upgrade failed

switch stocks in bootloader mode, timeout, linux, debian, ubuntu

Upgrading a Netgear switch can be very annoying…i’ve recently bought a second GS108Ev3 and wanted to upgrade the firmware initially but the switch stocks in bootloader mode (still web accessible on 192.168.0.239). By running the upgrade via Firefox or Chromium on Debian the firmware upload stops at ~7% with a timeout error. Same issue with tftp.

Solution#

Use a Windows Machine (Win 10) + Google Chrome Browser and run the firmware upgrade procedure via web interface on 192.168.0.239 – this will even work in case the Netgear ProSAFE Configuration utility throws a timeout error. VERY WEIRD!

Overall the (first) switch performs very well over the last few years and draws very low power – a great SOHO product with VLAN capabilities (PVID/Tagged/Untagged) but the firmware needs a makeover..

External USB 3.0 SSD with Full Disk Encryption

Preface# External USB drives are everywhere these days, used as storage extension, data transport facility or backup drive. If you need a reliable, schock resistent and secure solution an external SSD might be the best choice instead of an old fashioned hard drive. Especially in case the drive got stolen, a SSD can protect your data […]

HowTo: Flashing NodeMCU Firmware to ESP8266

esptool.py, nodemcu, ubuntu, debian

NodeMCU Firmware# From time to time, you should take a look into the official NodeMCU Firmware repository. It is under heavy development and new modules and features are added constantly. Since version 0.9.6, there are no binary releases available, because the large amount of available module will not fit into the flash. Instead, you can […]

Firmware Update of IBM ServeRaid BR10i with Ubuntu

system x, x3550 m3, LSI SAS 1068E, ibm 7944

I have just got a used IBM x3550 M3 server as development machine and ran into some trouble when trying to add some SSDs: the throughput was pretty slow (~100MB/s). Generally the BR10i controller supports 3G SATA2 and therefore i expected a throughput of ~250MB. I’ve figured out, that this behaviour is caused by the firmware […]

pcb assembly failure, low reflow temperature

Death Android Tablet..# Today, on my way home, i would like to read some stuff on my Lenovo Thinpad Tablet 32GB – but.. i can’t turn it on. The power-button/switch doesn’t gave any haptical feedback. So what’s going on ? I very like the robustness of the tablet and of course..it costs around 600€ half […]

RapidFire Controller Signal Analysis, “Secure” Rapidfire Mods

Big Brother is watching you!# Did you know, that a standard RapidFire controller mod is fully traceable by the game software ? No ? But it is true.. The trigger-signal-waveform can be analyzed as well as the statistical distribution of the trigger-down-time. In this post i will explain how it’s traceable and show you the […]

Motivation# Of course, there are several rapidfire mods on the web but most of them doesn’t work as exceptet: they only operate in a few games, they are traceable by the game software, you have an addiotional inconvenient firing button with a longer responsetime as the normal trigger, and so on.. With this mod you […]
