One rare possibility could be you triggered some of the infamous UEFI bugs, that already killed some series of Samsung and Lenovo notebooks. It works like this: UEFI specs propose a non volatile memory (nvram or eeprom) that can be accessed by the OS to store settings or debugging information. Linux actually uses this feature in case of a kernel panic: If ...
I pronounce it bi-Ohs (bī'ōs)
No, it is not possible to destroy the BIOS (legacy or UEFI) in this manner with that command. Even if you somewhat managed to destroy the UEFI partition, core BIOS files will not be affected, as they reside in non-volatile memory (flash-based, mostly) socketed on your motherboard. UEFI partition hosts additional software components (eg: debugger, driver, ...
I would use an industrial IDE SSD...(another option). It doesn't sound like you need much space, and there are SSDs made specifically for this purpose. I would NOT bother with IDE adapters and consumer-level SSDs for this application. If you do go for compact flash, again, try something that's purpose-built for the application.
It does make a difference, it will only make sense if you require the RAS (Reliability, Availability, and Service) features on x4 or x8 devices and understand the trade-offs for your needs. More details can be explained in the Dell white paper Dell™ PowerEdge™ Servers 2009 - Memory. Also, configuration and layout with details specific to the R710 are ...
Does it have to be a SATA SSD? CompactFlash cards are pin-for-pin compatible with the ATA standard 1. Which means you can use a passive electrical adapter to connect one to an IDE cable (or two!). Would this give you enough space (I've seen some mahoosive CF cards...), I wonder. It'd give you the reliability of solid state memory, and the oldness of ...
The Blue Pill was a proof of concept, that this could be potentially used by malware, making that malware completely invisible to the OS.
With the HP ProLiant G5 and newer (G6, G7, Gen8) servers (e.g. DL380, ML370, etc. - Anything after the Intel 5400-series CPU's), it is possible to disable half of the cores available to the server. This is a BIOS switch labeled "Processor Core Disable" with options "All Processors Enabled" and "Disable One-Half of cores per Physical Processor." This is a ...
There's no option here. Since the advent of the Nehalem and newer CPU's, the POST time on HP systems has grown tremendously. I see that you're using this as a workstation. Is there any option to leave the system running and take advantage of some of the BIOS power management options?
Interesting question... In general, I base the system performance profile on the application and intended use of the server. I typically work with: Low-latency transaction-heavy systems. Virtualization hosts (VMware). Linux-based ERP servers. The systems that require deterministic performance and low-latency are typically set to a high-performance ...
The M610 (and all Dell 11G or later servers) has a built in UEFI based utility called the Unified Server Configurator (USC) that you can boot into (by hitting F10 at startup) that includes the ability to download and upgrade the BIOS. There are full instructions on how to use it in this Dell support document. The appropriate OMSA Live CD will do the trick ...
This is outlined in the document you linked under the "Tuning Procedures" heading. In order to enter the Advanced system options menu for modifying a G6 or newer HP ProLiant for a low-latency application, you need to get to the main BIOS screen by pressing F9 during POST. Once there, type Ctrl-A. This will present an additional menu named "Service ...
While fun, rm -rf / can only break a havoc inside its own little jail -- and that is the partition(s) it is given. It cannot mess up disk MBR, nor it cannot magically destroy your computer. Something else is wrong in your case.
You will have to access the information available on your managed switches. If you have an unmanaged network, I don't see a way to do that. This is assuming the target computers are capable of Wake-on-LAN (WoL). In this case, a link to the server is established (look for the flashy link LED), and the network card is listening to WoL broadcasts. AFAIK, the ...
You won't be able to disable the VGA graphics in the bios unless you have a secondary card pci/agp graphics card installed. You might see the option, but it won't let you do it unless there is some other output. If your bios is fancy it might have a serial output in which case you might be able to disable the VGA, just be ready with a serial console if you ...
Nothing. HP's proliant servers simply are very slow at booting. G7 is even worse and G8 (just testing them now) hasn't improved things either. It looks shinier, but is slower still to boot.
The other answers seem to agree that wiping the BIOS is probably not your problem, so here's another thought: My computer, when switched into UEFI mode, skips the BIOS screen completely. No manufacturer's logo, no nothing. It just tries to boot and tells me there's no bootable media (or boots). If I remember the key to enter setup, I can whack it as the ...
You could consider running VMWare ESXi on the hardware, and only present 4 processing cores to the guest. The "overhead" should be negotiable as there would be four free cores.
If the machines are not powered up, this is impossible. If they are powered up, I would guess this is impossible as well, as you need a minimal network stack to at least answer things like ARP queries etc, which isn't working without an OS installed. What might work (I don't know and can't test right now) is that the NIC and the switch communicate when ...
Are you sure that you bought it with a PERC? It's optional, it might not be in there. Crack open the box and see what you've got. If you hit F2 to go into the BIOS, you can also see what's configured there. I suppose it could be physically present but disabled in the BIOS. As you found - the BIOS was configured to not use the RAID adapter. Once you enabled ...
Midway through the POST process, you will see a prompt to press F9 to enter the system's ROM Setup Utility (BIOS screen). The machine will also emit a double-beep at the end of the POST phase, giving another 2-3 second opportunity to press F9 before the system boots the operating system. Either way, it's F9.
Please see: Oracle Linux 6 kernel panic boot - anything I can do? This is a harmless message. HP and Red Hat insist that you can safely ignore the error. But in general, the most current firmware is available here. You may also want to download the HP Firmware DVD to update all of the components in the system.
That above, or place a sticker between the laptop and its hard disk holder case. You cheap bastards.
use dell omsa live cd from dell.. it works very well for me [ although i use only poweredge rack servers, not blades ], is based on cent-os and lets you apply all regular firmware/bios updates meant to be run redhat.
Use the HP Service Pack for ProLiant. It's a bootable DVD image, which will upgrade all the firmware on your server, including the BIOS. If you don't have a DVD drive, or don't want to use one, you can use the HP USB Key Utility on a windows computer to create a bootable USB key from the image. A third choice is to use the iLO console, and mount the image ...
FYI: I got through it ok. In my setup, I installed GRUB on both /dev/sda and /dev/sdb, and it worked swimmingly.
This turned out to be a very interesting question. There are lots of links out there on this topic but they are ambiguous in describing the difference/relationship between the two. Best description I've found of the hard drive configuration for a Windows OS is this one: http://www.ntfs.com/hard-disk-basics.htm. It appears that MBR and Partition Table are ...
Use a supported PCIe SSD. Your problem is likely due to the hardware not addressing the PCIe x2 interface correctly. To verify the situation, look in the Rom-Based Setup Utility (RBSU - press F9) bios screen and see if the card is detected. If it does show up, then your issue is at the OS level. Update your server firmware if you haven't already, just to ...
Unplug it, unrack it, and throw it away. It's so old that Dell won't support it. You should replace it with a more modern R320 or similar, which would also be way more power efficient.
In German (my native language) I pronounce it BEE-os, in English I pronounce it By-os. In any case, with an O-sound.
