Many times just doing an update-grub may find Windows and add it to grub, but a lot of times it won't.
Create Windows in a custom grub entry like below:

}

Step 1.) Upgrade to Debian 11 first
The process to go to Debian 12 is not as smooth as 11, when trying to upgrade from Debian 10. In fact, it doesn't work directly, so you'll first need to follow this guide to update to Debian 11, reboot and come back here if successful.

If you have swarm services and dockerd is creating a high load even with the containers just being idle, the easiest solution is to upgrade to a newer docker version.

If I create the same setup on Debian 11, with Docker 20.10.5+dfsg1 then the CPU usage is low.
One other difference I wondered is the kernel. In my test setup........

1.) Create your EFI/ESP Partition
If you happen to have some free space on the drive already then this is easy, just create a new partition of at least 100M.
The nice thing about the EFI spec is that it must just be in the first 2.2TB of space so for most users, it means you can simply resize the last partition(downsize it by 100M) and then add an EFI partition at the end.
For example if you had this partition scheme:

Linux Mint offers an easy and painless upgrade path through the last 3 versions, which means no more reinstalling to stay current with the latest version.

To enable amdgpu we have to set special kernel boot parameters.

I think this is more so an issue with kernel modules not being included. I had this issue on Linux Mint because a new kernel I upgraded to DIDNOT have the "extra" modules and part of that reason is also because older kernels are named differently than new ones.

If you were previously........
I don't consider a lot of these "extra" kernel modules "nice to have" as they often contain drivers for essential items like your soundcard, your NIC and many other devices that may not work. Sometimes you may find that "sound" or "ethernet" worked before a kernel/OS upgrade and now in the new version they don't. Often it will be because you need to install the "extra" kernel modules.

Just add at least 1 of the new drives to the array, update grub/install it and then boot into it. Then you have a transparent data migration that is fully synchronized.

I've got one of these for testing projects from work at home and got more than I bargained for with the time I've spent on it due to the storage handing/Perc 6/i cards.

One thing to remember is that you need MegaCli to do the flashing.
You also need the correct file,I tried at least 2 different Perc 6 firmwares from Dell that kept getting rejected as corrupt by MegaCli(they were really the wrong version). I have an external PCI-E Dell 6 Perc/I butI chose images from the 'Integrated" on motherboard version as it was allI could find. They are different, and below is my first time finding success.........
I flashed an LSI Logic firmware to it and it broke the BIOS (cannot do Ctrl+R) for booting purposes but allows other functionality to work normally.
I tried downgrading to a Dell firmware for Perc 6i but it won't work, not even with MegaCli

At first it was configured as a RAID 0, then I deleted the Virtual Disk Group.
I thought both drives would be shown and detected in Linux as sda and sdb but it actually shows nothing.
To make them work you have to hit Ctrl+R before the system boots (when prompted) and create a Virtual Disk Group. In my case I created each one as RAID 0 (with a single drive only) as I just wanted JBOD but there is no such option or default in these Dell Pe........

Usually a lot of things don't work right on Linux, but Samsung printers aren't one of them. I used to have a CLP310N that never worked right in Linux, it would print strange lines over pictures or with some programs, no picture at all. I was using whatever the default driver that Ubuntu found.

This may sound silly but there will be conflicts/issues with the default Centos repository so you have to use a third party like remi (I prefer not to do this but it's the only option unless you migrate your sites/data to another server or can stand some downtime-not an option IMHOon a production server).

The correct version of one or more libraries needed to run VMware Server may be
missing. This is the output of ldd /usr/bin/vmware:
linux-gate.so.1 => (0xffffe000)
libm.so.6 => /lib/tls/libm.so.6 (0xf7fbd000)
libdl.so.2 => /lib/libdl.so.2 (0xf7fb9000)

Upgrade Release Kernel TipsThis is for CentOS 3.1 to 3.8 but the methodology will apply everywhere.
I ran into a problem first of all with a non-booting system after running
#yum update centos-release
It took me to 3.8 and upgraded all the other packages [b:7e931c835d]BUT[/b:7e931c835d]
because of some stupid flags enabled in /etc/yum.conf the KERNEL WASN'T UPGRADED SO AFTER BOOTING, WELL IT DIDN'T BOOT OF COURSE :)

How to compile in Windows/DOSMingW is a free compiler project so start here:
http://www.mingw.org/download.shtml#hdr2
I downloaded the core GCC compiler:
http://prdownloads.sf.net/mingw/gcc-core-3.4.2-20040916-1.tar.gz?download
But it's missing even the standard C runtime libraries like "stdio.h"!
You may also need to add environment variables from the DOS command line.

Chipmaker Intel (NASDAQ: INTC) has successfully topped the personal computer market for decades. Breaking into related areas such as communications has been much difficult for the world's largest semiconductor maker. But a new partnership with Nokia (NYSE: NOK) could help to change that.
Intel's forays into cellular-phone and home-entertaiment-device chips have........
Upgrade FreeBSD/usr/source/
make build world, make build kernel, make install kernel, make install world
I'll test this later on and see if it works!Here is a good guide to update FreeBSD:

CVSUp the Easy WayIf you're reading this you probably have never used CVSUp or don't know how.
CVSUp can be used for two things or just one if you prefer.
*Keeping your kernel up to date
*Keeping your port list up to date
Start by editing the following file in:
[b:76928b387d]vi /usr/share/examples/cvsup/cvs-upfile[/b:76928b387d]
It can be quite overwhelming with all the crazy options.
Basically there are only 3........
Telus Begins Enforcing Bandwidth CapsIt appears Telus has begun to send e-mails out and is planning on enforcing bandwidth caps of only 10gigs/month for their 1.5mbit plan and 20gigs/month for 2.5mbit
The state of Canadian ISPs is horrible :(
In the east coast, Bell Sympatico will allow you to have unlimited bandwidth and even Aliant will and they have 3mbit for a much more affordable price than our 2.5mbit on Telus.
Telus needs to get wit........
I played around with xmit power (how much power in mW) to see if I could increase the range and signal strength. Idon't think this Linksys WRT54G's strength is the wireless, it seems to have poor signal quality and transfer rates all around.
Ithink part of the problem is also that there are several wireless networks around my house that could be interfering and the walls are thick here.
Anyaway, moving on now :) The default is 28mW and I increased it to........
The "Geoip" package is available on virtually all Linux and Unix like systems and is very handy in looking an IP address' corresponding country.
The homepage of the maintainers is here.
They also have a package called "Geocity" which can be downloaded from their site, it is still free and gives you a close indication of the city the visitor is from. You can........
Everyone says there is a "manual" way of doing it and then they tell you to use iTunes, but if you're like me, you're travelling on business in a foreign country and your laptop does not have iTunes and you don't have a way of getting it and/or don't want it.
For this example I'm using the provider "du" in Dubai, UAE (United Arab Emirates) but this method works for virtually all providers.
The requirements in this case to truly "manually update........

Itried everything Icould think of, and of course even with the NIC enabled in the BIOS nothing was working. The light would flash when you plugin the cable for a second, but that's all.
Due to another issue I'm about to post about (server is not compatible with 1TB/1000Gig Hard Drives), I updated the BIOS. I didn't even know the 100mbit NICs were not working untilI decided I should test each NIC one by one.
Inoticed that only 1 server out of........
Have you ever seen this dreaded message in your Apache/HTTPD /var/log/httpd/error_log?
[error] server reached MaxClients setting, consider raising the MaxClients setting
The error itself is slightly misleading. Ibelieve this happened to one of my servers, I found Apache was running still, and that you could telnet to port 80 but no respnose would be given.
For some reason my error log initially did not have the above error, but after a restart I saw........
Truly, the only way to unleash the capabilities and customization abilities of iPhone are to jailbreak, it's not just for hackers anymore.
A few days ago someone by the named of "geohot" released a single click application called "purplera1n", which does the entire operation smoothly and seamlessly.
In our case, the first time it went as far as "done, wait for reboot" on our Windows machine and for minutes we waited and saw the pic on the iPhone w........
Yes, Iadmit I finally got bitten by the hype as much as I can usually see through it all. Keep in mind this review is of the "stock" phone, no jailbreaking yet which is what really unleashes the customizability and whyI bought iPhone.
I had better things to say about this phone before buying it, and it is a great phone, perhaps the best on the market by far, if not because of the Mac OS port onto the iPhone and all the apps, etc, etc.
With that said........
The dmg format is silly and annoying to work with, why couldn't Apple stick with the .iso standard? Anyway, there's an excellent Linux and Windows based tool to convert it back to a normal .iso Image called dmg2iso
I'll only cover theLinux version although the Windows pre-built binary works the same way.
Download dmg2iso here for free (from the author's website)
It's just silly and doesn't make sense that Ubuntu doe........
When trying to even cd or ls the mounted OCFS2 partition it crashes. Ithink this is a combination of VMWare Server's problem and the way I mounted and symlinked to it.
More than anything this shows the problem and lack of forsight with VMWare, but also that OCFS2 is easily crashed if you do strange things.
