While working on a project where a fast microcontroller with Power over Ethernet capabilities made sense, I discovered the TTGO T-Internet (also known as T-ETH) PoE ESP32 board on Aliexpress.

I have used the TTGO T-Display in the past so I figured I'd give it a shot. In order to implement it in my design I had to …

Have you ever been lazily sitting playing Nintendo and wanted to reset the console without getting up? I have, and I thought there had to be a better way... Using a cheap Arduino Nano (ATmega328) clone from Aliexpress, a few wires and a little tinkering, I created a solution.

This device passively reads the clock, …

Update: Thanks to Google Books I found a reference to this game in the book "Brand Leadership: Building Assets In an Information Economy":

"IBM sponsored an interactive sports game, the Shockwave IBM Virtual Dunkathon, on a number of sport- and game-related sites (such as nba.com) to attract young, …

After fumbling around for a while trying to mount an ISO on my Supermicro motherboard IPMI, I finally figured out that it requires SMB1 in order to mount.

SMB1 is an old and potentially insecure protocol but if you wish to enable it here are the steps.

• Navigate to Services and click on properties for the SMB service. …

In an effort to increase the performance of a generic 4 port PCI-E USB 3.0 adapter I bought on eBay, I went down the rabbit hole of flashing newer firmware on it.

After several failed attempts at using the VIA flash utility (see links below), I realized I had to determine which SPI flash was on my card. In my case it …

If you have a Dell H200, IBM M1015 or other rebranded LSI 9211-8i HBA, you may run into an issue flashing IT firmware due to the error message "Cannot Flash IT Firmware over IR Firmware".

An example of such an error:

 1fs0:\> sas2flash.efi -c 0 -o -f 2118it_19.bin …

Now that the Dell R210 II is unsupported, obtaining firmware is tougher. I was able to generate a bootable ISO using Dell Repository Manager (DRM) which contains the latest firmware updates as of December 2019. I am publishing it here hoping it is useful for somebody.

This worked for my system but your mileage my vary …

I was unable to get esxcli, storcli or MegaCLI to display my 9211-8i (IR mode) adapter information in ESXi:
