Hardware / Troubleshooting GenMAC/GENMU

« on: October 16, 2024, 04:42:11 pm »

I have no prior experience with WIFI under OS/2, so do not expect any prior knowledge.

I recently put a Intel 5100 mini-pcie card in a computer. This card has an PCI id of 8086:4237. Booting into a linux live distribution I can connect to my wifi network and also a number of neighboring networks are visible (signal strength is not that good, but I do get a connection). From what I gathered this particular card is officially not supported by GenMAC, but should work with the GenMU package for intel cards. In addition the xwlan widget should be used.

I got the GenMac driver loaded on boot. It says: Loaded for Device: Intel 5100 a/b/g [8086/4237] ("WRND32"). So I suspected all is good.

However I am unable to find a wireless network. Not with the xwlan widget, not with the GenMac provided scan.exe
I am not sure how to proceed/troubleshoot. It seems to me I should first get to a point where I can query a list of networks, before continuing to configure the xwlan widget/wpa supplicant.

Any help?

Programming / Rexx Programmer's Reference, 2nd Edition now freely available

« on: October 14, 2024, 11:35:45 pm »

Just stumbled upon: https://freecomputerbooks.com/Rexx-Programmers-Reference.html

which is the second edition to Howard Fosdick's Rexx Programmer's Reference. Apparently it is licensed under a Creative Commons license, which gives you the possibility to obtain the book free of charge.

Hopefully (my wish) there will be a printed version of the book in the near future.

Virtualization / Setting 4k resolution for VMWare guest

« on: August 16, 2024, 06:27:54 pm »

I recently acquired a thinkpad with a 4k screen. I have a OS/2 vm in the latest and greatest VMWare Workstation (which is nowadays free of charge for personal use). However I cannot find a way to make my full screen resolution available to the guest VM. I tried editing the vmx file, but the darn thing keeps reverting to 16MB of graphical memory, which obvious is not enough for 3840x2160. Most pages on the web advice to install VMWare tools in similar circumstances, however they are not available for OS/2.

Anyone got any clues on how to solve this problem?

Programming / How does AVIO works?

« on: March 24, 2024, 05:37:42 pm »

I just read heard about advanced VIO, what I gathered so far, is that you supposedly can create an AVIO presentation space with VIOCreatePS (see https://ia801901.us.archive.org/13/items/OS21.xTechnicalDocumentation/64F0276_OS2_V1_2_PTI_Presentation_Manager_Programming_Reference_Vol_1.pdf page 467). If I understand this correctly it should be possible (in 16 bit apps at least) to incorporate an area in a PM application, that can be populated (updated) with VIO calls.

Anyone knows something about this? Maybe someone recalls an article or an example from back in the day?
