Thanks for quick reply! Hmm, I did yet another fresh install of 95C without installing your patch. 1. Of course monitor USB hub is connected to PC. I am not stupid enough to believe that monitor driver will suffice! LOL! 2. I cannot remove the USB extension card, because I use this PC (I am posting from it now)! I have 2GB memory and didn't use rloew's patch. I just wrote: MaxPhysPage=30000 (=768MB), which is displayed correctly in 95C. Now it gets more funny: Even without your patch I received an insufficient memory error when trying to run DOS prompt from Start menu, or a couple of DOS programs from Run. But I can Run edit, chkdsk, etc. Also typing 'command' in Run gives me the DOS prompt without issues. A 'mem' gives: total/used/free: 66MB, ?, 768MB. Yes I saw the inf's, but if they don't work, as you stated, no need to bother about them. Missing LAN is bad though:no shared folders, no internet. Anyway, no big problem. I installed 95C for fun and to run old stuff (read mainly games) without opening some other vintage PCs I have installed it to (to avoid con/discon cables for CRT, keyboard, speakers, ...). Let me see if how much memory is displayed now when I go through F8 directly to command. Something goes wrong there.
