The more Microsoft tries to tighten its grip, the more users and will slip through its fingers....

That sounds like a quote from Princes Leia to Darth Vader (or the evil head guy of the Death Star; I don't remember his name).

There is one way I can think of to make VM workable as a primary platform (even if not desirable). Take something like freebsd and set it up to only bring up VM. Then you could launch OS/2, maybe windows, and even freebsd or linux within that structure. It would be done in such a way that there is no base OS that would be usable as such... just the guests, similar to VM on the mainframes.

Ding, Ding, Ding. We hava a winner!

Another example is "microcode". It is a software layer underneath the OS (between OS and hardware). It insulated the OS from much of the actual hardware such that you could change hardware architecure and not have to recode the OS.

PCs just repeat mainframe designs 20 years late (but at an affordable price).

Make it so.

Again.. the problem with this all is CPU cycles, anytime you put another layer in you slow things down. And again, having an emulation layer which dumbs thins down to a level which an older OS can understand (without updated drivers) is just the same thing as going out to a store and buying an older device. There will be no benefit from it. I can see advantages in certain points if done right:

The Host OS installs printing support and a virtualizaed network, you print through the guest OS using a standard printer interface. (this is pointless is we have cups)

The Host OS connects to the physical networking device and allows you to connect through a virtualized driver. (this is actually GOOD =) however it kills the ability to truely use the guest as a server, since the overhead is unacceptable under such conditions).

The Host OS controls the HD's, and virtualizes hardware access so that an older guest OS can make use of such hardware. However, there is a likely hood of corruption under heavy use. If the file system driver doesn't have a hardware level hook there is a chance (pretty good one with certain journalling file systems.. ::cough: that things can go quite wrong in a quite indetectable fashion.

I'm not going to even get into graphics hardware, due to the many layers involved even with native drivers you are just going to stack up overhead on the graphics hardware and the video hardware.

Hey.. I never claim that virtualization doesn't have it's uses. But again.. the real world useage is hard to determine, along with the fact that many people don't want to pay the price of entry. Could virtualization help people who already own eCS or similar operating system and wish to keep using it on newer hardware. Yes.

Will it help a company like SSI stay in buisness and gain NEW customers. Unlikely.

Have you TRIED virtualbox's "accelerate video" I have. The 3 OS's I tried on it (one actually being winxp) actually have faster video in VPC/2 then they did in virtualbox on XP. (and the winXP machine is a AM2 4200+ (x2) and the OS/2 machine is a Athlon64 754 3000+ =)

Looks like Parallels has fallen behind Innotek. Parallels does not expect to have video acceleration for a couple more months.

... excerpt ..
when might we expect the next major beta (key word here being "major") and he said that it should be within the next couple of months. There will be a few incremental releases in between (here was even one released today! Build 3120), but the next major beta should bring us a lot of cool stuff that many users have been asking for.

Such as?

Much to many of your delight, hardware graphics acceleration is expected to come in the next major beta, which as I said in the paragraph above, will be available within the "next couple of months.

"Told you so" moment for obiwan:


obiwan (28 Nov, 2006 02:43):

Some folks have been working independently on their own OS/2 video drivers. SciTech has worked so well that these efforts have been largely isolated and unnoticed. If SNAP does decline, the good work of independent driver developers will attract recognition, support, and hopefully improved collaboration. This is good because SciTech was never going to expand the feature set of SNAP on OS/2.

We should be past using the "D" word by now.


See Alternative video drivers for eComStation posted last week.

Sometimes I even impress myself.

If it expands to support other chipsets, I could see it as a possible replacement for SDD. The future of OS/2-eCS is looking better.
