Is there a TCP/IP stack and drivers for it? I've ran into a download in github issues posted by what I presume is the project leader, a zip file containing packet drivers and some preferences, I've extracted it over and see no change, looks like modem is the only connection thing available.

I was also trying to increase refresh rate by using external tools such as univbe+unirefresh or vbehz.
Unirefresh constantly calculates a bit larger values and drives the monitor out of sync. Vbehz seems to be able to spit out a correct refresh of 85Hz when I input the pixel clock setting from monitor documentation. But there seems to be no change in GEOS. I am using an SVGA mode 640x480 8bpp so it has to use VESA.

My card (ARK1000) is not capable of VBE3 so I have to run UniVBE.
