Rollback RX vs GRUB

I became concerned if we were still in Pentiumland, so I asked him, "when you say 'D,' do you mean 'Pentium D?' I don't want to change that, but otherwise, I'm still happy with the setup."

He just answered, "yes optiplex 620 Pentium D, duo core."

So I think that settles things... do you?

Intel reused the word "Pentium", for their recent budget processors, because there's "Pentium Dual Core" as well, which I believe is actually a Core 2 Duo but with less cache RAM. Pentium was intended for their line of CPUs between "Core 2 Duo" and and the very budget "Celeron" line. But now they've changed again with the "Core i" series, "Core i3", "Core i5" and "Core i7". Not quite sure where the "Pentium D" fits in though, although I've seen it in budget laptops.

Pentium was originally for Intel's 5th generation 586 series CPUs, which came after the 486s. "Pent" implying 5 or 5th generation I think, fake Latin. :D ...something to do with that they can't trademark numbers, like 386, 486, 586, so they had to give it a name and register it as a trademark.
 
Well. neither the seller or me know its age, it and a zillion others came from the NC state guvment, or so he tells me. But I'll know what it's like something like next week; might even start a new thread to brag... or scream... or yawn.

I have no idea if I just did the right thing, but I learned as much as I could as fast as I could, then crossed my fingers and made a few decisions.
 
That depends on what you wanna do with it, as always. The Pentium D is actually 2 P4's duct-taped together, so anything feature wise the P4 lacked, you'll still lack here.

Namely, since you've been trying out a bunch of linux distros, you may find a relative lack of speed in using Virtualbox to test them, should you do that. This is because the cpu lacks full hardware virtualization support -- so no hardware acceleration in virtualbox. You may have some options to enable in the BIOS, but in my experience the hardware tab in virtualbox is still greyed out when using that setup. Go figure. :confused:

Playing todays games with that cpu is kinda weird. Even if you have a semi-modern GPU, they'll still be CPU-bottlenecked, (read: LAG) even though the P-D is two 3ghz cores. This is because the amount of instructions they are able to process per-clock is still vastly small compared to modern cpus -- modern chips' high instruction-per-clock amount is the main reason most systems can get away with being clocked in the 1-2ghz range while still outperforming last years' models.
 
Good info up there...

I still have a feeling that I should've stayed single-core, but that's just because I'm familiar with it. That and I made those decisions way too quickly and practically expect them to be wrong now.

Oh well, I still think it'll be considerably faster than my ten year old single core USB1 doormat. And it's too late to worry about it now, cuz it's on the wagon.
 
Don't worry about the the single-vs-dual core issue. Even if the PentiumD is from the same P4 architecture, you'd still want to go dual/multi-core. Purposely choosing single core these days is like purposefully choosing a unicycle instead of a bicycle to ride. :cool:

With a multicore-aware OS like win7/8x or modern linux, you'll still be able to multitask better than on a single-core. Though I suspect in your case the difference between a HyperThreading P4 vs a PentiumD may be somewhat negligible, but then again I've never done the benchmark research either. Not all P4s had HyperThreading for that matter, either.
 
3 pieces of evidence point to jet's takeover

TRANSPONDER
One clue is that the plane's transponder - a signal system that identifies the plane to radar - was shut off about an hour into the flight...

ACARS

Another clue is that part of the Boeing 777's Aircraft Communications Addressing and Reporting System (ACARS) was shut off...

GUIDED FLIGHT
The third indication is that that after the transponder was turned off and civilian radar lost track of the plane, Malaysian military radar was able to continue to track the plane as it turned west...
 
Some time ago, I started this "Rollback RX vs GRUB" thread because I had no idea what I was doing. With a lot of help from y'all, I managed not to only get Rollback and dual-boot both running, I learned about distros on a stick, more somethings, and finally I decided to upgrade my tower: double the ram, double the cores, double the bits... and now I learn that the 32>64 switch will probably force me to PAY MONEY for an upgrade to Rollback!

...if I had known that then.
 
....No, 64 bit cpus can fallback to 32bit mode when presented with a 32bit program running....you should try to see if Rollback can handle booting 64bit windows/linux. You've got nothing to lose. :cool:
 
[FONT=Verdana, Arial, Helvetica][FONT=Verdana, Arial, Helvetica]I get a feeling that they both might think I'm getting a brand new PC, but I ain't. It'll be here soon and I'll just try my current version and see if I can stay free.

Based on the email [] address, we found that you have version 8.1 of Rollback Rx which will not support 64bit Windows, and most the new PC now come with you Windows 8 or 8.1 so most likely you will need to purchase another license for your new PC.

Reply #2:
Rollback Rx v8.1 was only compatible I believe until Windows Vista and partially with Windows 7. Since version 8.1, there have already been two major releases (version 9.X and version 10.x). Also if you're buying a new PC more likely it would more likely have UEFI BIOS and use GPT partitioning which only our current build (version 10.2) is compatible with.

I think I can practically guarrantee that that PentiumD chipset is not gonna be an UEFI board. :p

Their responses seem to indicate they've never really tested it on a BOOTMGR-style bootloader like the one Win7 has. The non-UEFI versions of 32/64 bit win7 uses the same exact BOOTMGR and associated files, with the only difference being they were compiled for 64bit, in my experience.

I think you mentioned you were able to get Rollback to launch your win7 copy, correct? If so, that means it didn't have any trouble identifying the neccessary boot files. The same should occur on win7 64bit, but the moment of truth is whether it'll successfully chainload and launch it or die on the bit/environment mismatch.
 
I think you mentioned you were able to get Rollback to launch your win7 copy, correct?

A W7HP OEM disc, yes.

[edit] When booting, the Rollback splash shows right before Grub shows, but if I tweak the Grub menu, Rollback doesn't load at all, forcing an un-/re-install.
 
Never mind... again. I deserve it for gambling on used PCs. It was slow slow slow and the fan was loud loud loud. I guess I do this so I can appreciate my ancient HP, which can do anything, if I have all day.
 
You know, with your win7 disc you can go ahead And by a new win8 rig, modern hardware and all, and use the win7 disc on it. Plug the machine's win8 key in the 7 disc and it'll accept it without complaint. :D
 
Oh. My. God. Joel has provided a solution! Wish I knew that a year ago, when I had a W8 beast for one day. But it's still good to know for next time, or should I say next weekend.
 
Yes. Alternatively, you can boot up the win8 system, install and run "magical jellybean key finder" to extract the win8 product key so you can write it down.
 
From what I've googled, I find that How to downgrade Windows 8.1 to Windows 7 is a very popular subject. But most of the hits say you need W8 Pro to do it. And all of them have a much longer list of steps than your one step does.

I think I'd be shelling out a lot more money this way and just hoping you were correct. So I'm safer to just keep poking around for W7HP PCs, which, curiously, are getting more popular as time goes on... muttering that my old cutting edge box is terrific, at least it was ten years ago.
 
Why not use the key that you're currently using right now? As long as you wipe 7 off your current rig you can place it on a win8 machine that way. Since you legally own that key you can use it as you see fit.
