Not 100% sure since we've overwritten the version variable, but we're up to this commit: https://git.ipxe.org/ipxe.git/commit/f55...1d10e6f0c3

I had no idea that was even an option, but I just tried and received an error: Could not open SAN device: Error 0x420e2001 Looking at the documentation, that refers to: You get this error when tryin...

  Thread: Alternatives to using Memdisk?
Post: Alternatives to using Memdisk?

We currently use memdisk as the kernel to load BIOS update images in iPXE to perform BIOS updates. Unfortunately memdisk doesn't seem to work for Lenovo BIOS updates (ISO or .IMG) in any combination o...

  Thread: Embedding a variable upon compile
Post: RE: Embedding a variable upon compile

Thanks for the answer - I wonder if there's an easier way to do it and if there's a way simply pull the baud rate directly from an iPXE shell? e.g. it's already in a variable somewhere that I can echo...

  Thread: Embedding a variable upon compile
Post: RE: Embedding a variable upon compile

True that - however, that does require me to have a completely separate script for each serial speed variable and keep each of them up to date if I want to make any changes. I would like to use a sin...

Post: Embedding a variable upon compile

I'm just curious if it's possible to embed a variable when compiling undionly.kpxe We have a situation where we need multiple serial baud rates - we have the ability specify which version of undionly...

  Thread: Reading the BIOS version in iPXE?
Post: Reading the BIOS version in iPXE?

Does iPXE have a built-in method to read the BIOS version of the machine it's loaded on, much like it can read the serial number, manufacturer and product in the configuration settings? I'm thinking a...

  Thread: Setting serial speed/Baudrate dynamically?
Post: Setting serial speed/Baudrate dynamically?

We have multiple machines with both 9600 and 115200 Baud rates. I'm curious if there's a method by which I can set this dynamically in iPXE, either through autodetection (unlikely), or by changing the...

Nope, this is all with the default git branch and I began by trying to chainload into iPXE. Honestly, this just looks like some kind of bios SNAFU with lenovo, since it does work once I update the bi...

We're using BIOS mode for our iPXE images for maximum compatibility across all devices. I find it fairly strange that the USB NIC works fine without issue when the machine is at a higher bios versio...

Another update. I've downloaded the and I'm serving the default undionly.kpxe file from http://ipxe.org/howto/chainloading (that should technically result in an infinite loop if I don't set any dhcp ...

Some extra information. The moment I do anything related to performing a network action that's not ifstat (ifopen, dhcp, even a loopback test) iPXE stops - it doesn't quite hang, but I can't go back ...
