Windows Virtual Machines Kalhmera kosme.
I'm at the library right now and our NT workstations do not have international keyboard "drivers" installed. So I have to write Greeklish.

So, it looks like you get a console from the kernel whether you want one or not. I'm thinking of those virtual terminal "emulator" processes. It's gotta be possible to emulate an xterm in a vterm, then neanderthals like me can use their stone tools. > > I meant to say "utf-8". The irony is that utf-8 also blew up the Latin-1 characters.

What matters is the ability to type any letter used in any human written language. That is a very huge improvement. I agree.

The url is: http://ta-nea.dolnet.gr/ They don't use the 'www' prefix as an alias, and I keep forgetting their parent company name, 'dolnet'. (I asked them to register 'tanea.gr' but they haven't.) The Communist Party newspaper is: http://www.rizospastis.gr/ They have a much nicer name, and they also have a 'text-only' link which does not download images, just the text. You can get the entire daily newspaper through http. (Only I don't know if they are using unicode, but I assume not, it's probably ISO 8859 too. You see?

What you need is to emulate an entire system, like vmware does. I haven't been able to determine exactly what vmware does from their website, too proprietary, too hush-hush, but I assume they write VxDs which map the Linux kernel to the Windows VMM, and the real hardware. Someone once told me their product ran on the NT platform, but not Windows 98, but it was quite expensive. (All hearsay. No personal experience.) The heart of the Windows operating system is called the VMM(=Virtual Machine Manager). There are alot of descriptions out there, like http://win32assembly.online.fr/vxd-tut2.html When the VMM is running an instance of DOS, you get direct access to the DOS INT21 interface. Your program can even write directly into display memory, just like the old days, when your program owned the console. The VMM manages to control access to the real display, by remapping the "real" memory(=the virtual memory address space) used by DOS, which still has that weird 20-bit memory line. Even 32-bit protected-mode programs designed to run under a DOS extension called "???extenders???" --I forget the jargon-- still run in a DOS Window. Microsoft has managed to recreate the entire the DOS OS, not just command.com. I think you could host Linux, if you had the right VxDs. The VMM remaps the i486 ports used by the hosted OS's device drivers, so when the Linux kernel writes to port addresses, the VMM traps them in a VxD, which manages real hardware. Even the IRQ lines of the processor are emulated by the VMM, so hardware interrupts are trapped too. 32-bit Windows programs run in a "System VM", which is a bit more like a "monitor" than a (Unix) process. The IBM SP(="System Product") VM Operating System ran on mainframe hardware. Their VM hosted single-user systems called CMS(=Conversational Monitor System), but it could also run multiple copies of it's mainframe OSes, MVS, and DOS/VSE. I wonder if it could run another copy of VM in a VM. Each SP/VM got a 'mini-disk' which would be akin to a 'partition' under DOS/Unix, so the Linux disk driver could be fooled into thinking it was accessing it's own disk unit. It's fascinating technology, but you'd need inside information to make it work. Google isn't enough. Given enough time, I'm sure these VxDs will appear out of nowhere, as freeware or sharewhare or whatever it's called. > > Did you know Microsoft has removed unicode support from their accessory program, Wordpad, in Windows XP? > That seems particularly stupid a move. I should have said, "unicode text file support." Wordpad still does unicode, but only in Word format, not as a text file, so I can still edit a document in unicode, but I have to copy and paste it into a unicode editor to create a text file. __________________________________ Do you Yahoo!?
