slow ipxe menu - Elementelist - 2019-06-21 11:09

Hi all,

I have a couple of POS computers that have a slow text output when ipxe is loaded after the dhcp request.
When searching on the web i found a post that someone compiled serial console into ipxe that was causing the issue.
I've tried compiling ipxe without serial_console but the issue persists.

Many other POS computers with serial interfaces do work normal so im thinking this is an hardware issue but im not sure.
Do any of you experience the same issue?

Also i've tried to play with the baudrate when compiling with serial_console and text output gets even slower.
Anyone has a brilliant idea?
Thanks!

Best regards,

Dave

by default iPXE is not compiled with serial.
You might want to make sure there is no serial redirection or similar in BIOS enabled as well.

Is this in pcbios mode or efi mode?
Graphical output is genarally slower, but you might want to try and enable a graphical mode instead see http://ipxe.org/cmd/console (this requires change to compile time config as well)

Thanks a lot!
added the console option (with lower res) and the navigation in the menu is smooth.
Weird that only a particularly brand (NCR) seems to be affected.
The rest of the POS computers work without the console option.

I would still suspect console redirection setting in BIOS or similar
