Another issue that needs to be covered is the system clock. OpenBSD wants UTC, Windows wants local time. There is a FAQ item that explains how to get OpenBSD to deal with local time. In my Windows/OpenBSD setups, I try to go the other way, setting the clock with OpenBSD (which sets it to UTC) and trying to convince Windows to deal with it. There is a registry change to get Windows to work with a hardware clock set to UTC. This works correctly with Windows 7; see https://wiki.archlinux.org/index.php/Time#UTC_in_Windows As noted in this article, this does not work properly with XP or Vista. Also, it is important to take the suggestion to turn off the ntp client in Windows seriously. Windows should be made as passive as possible with respect to the hw clock; let OpenBSD take care of keeping the clock accurate by running ntpd there. I do not have any personal experience with Windows 8 and UTC. A little googling turns up messages that say the registry hack works the same as with 7, others that report problems. I suspect, but do not know, that the people that had problems failed to turn off the ntp client. Windows 8 vs. a UTC clock needs to be tested. I will try to do this when I re-arrange the machine described below. > > Sounds like I need to go buy a modern Windows system. :-/ You'll love it. I recently bought a Thinkpad T430 that came with Windows 8. You can easily find out what the weather is in Mumbai, but figuring out how to run an application is a research project. if the phrase "what were they thinking?" hadn't been invented prior to Windows 8, it would have happened shortly after the release. I did an as-delivered backup (in case I need to sell the machine) and blew the whole thing away with Arch Linux (OpenBSD doesn't support the wireless card; I've got another card coming that is known to work). /Don > > Nick. > > > >> >> >>> 17.11.2013 20:20 пользователь "Wesley MOUEDINE ASSABY" >>> <open...@e-solutions.re> Ð½Ð°Ð¿Ð¸Ñ Ð°Ð»: >>> >>>> Hi >>>> >>>> I just tested this.
