Re: What retro activity did you get up to today?

Spent all day with OleDb and MS Access, trying to create a table in a migration-like manner, and insert data in it. CREATE TABLE IF EXISTS ? -> Forget it. You've got CREATE TABLE, and you'll have to catch an exception if it already exists. A sensible DateTime type ? -> F* you. You'll get a type …

There is a CPU-World Discord channel, started by CPU-World members, and unofficially connected to the CPU-World forums. There is a fair amount of talk on old hardware, but most talk is related to more modern CPUs (engineering samples being a common theme) and overclocking. There is a lot of …
Re: Tualatin cooler compatibility

That cooler is for FC-PGA and others without the IHS, so wouldn't be suitable, unless you are willing and able to bend the clip so that it can cope with the extra height.
Re: Speaking of dual boot. The big trouble to put Windows 98SE and Windows XP in two different hard disk.
Posted on 2020-10-17, 01:42
Although it's not period correct, I decided that I will use a front bay loading CF-IDE adapter with separate CF cards for each OS on systems I want to multi boot. It's much mode flexible, and as long as I use the same CF card for each install on the same system, it's plug and play. It also allows me …
Re: AMD X2 3800+ build?
Posted on 2020-10-17, 01:36
I would replace it with a HD 5850 or a GTX560. I assume you are running WinXP? I don't think those cards exist as AGP. I'm pretty sure that HD4670 is the most powerful card that came in AGP, and it's not much of an upgrade from the 3850. The best NVidia AGP card is even worse - a 7900GS, with no …

Re: Questions about bootable floppies on old PC's
Posted on 2020-10-16, 03:00
I am sure there is a BIOS in the system, otherwise nothing at all would happen when you turn the computer on. I don't know much about proprietary systems, so have no idea how they differ from other PCs
Re: Questions about bootable floppies on old PC's
Posted on 2020-10-16, 02:57
I'm surprised it can ever boot without some kind of BIOS to get the PC to a point where it can read the disk. However, that's not your question. To create a bootable floppy containing the exe file, just take the bootable disk and copy the exe file to it. Then it will contain the basic files it …

FYI- I did not send any damaged bezels and I have the photos to prove it. The implication that I sent damaged bezels while holding back perfectly good ones is beyond insulting and would not be tolerated in a face to face confrontation. The damage occurred in transit. You have extra bezels ? PM me …

Does Media Player Classic work on Win 9x era hardware and OS? Comes with K-Lite Codec Pack, so plays anything.

Re: In an SMP system how does DOS/98 choose the CPU to utilise?
Posted on 2020-10-15, 18:38
I am surprised if any board or OS can function normally with multiple CPUs at different speeds. To me, it sounds like a car with left and right wheels at different speeds, they would be out of synch. It would involve some sort of overhead to make it work. Not saying it's impossible, just doesn't fit …

XP x64 was never mainstream so drivers wont be as optimised a the x32 variant XP x32 and 7 x64 is the most interesting as that's the common versions used but agree for fair comparison should be done on the same OS. I think the OS's are smart enough at this point that installation order matters, but …
Re: Dual boot Windows XP or Windows 7 32 and 64 bit?
Posted on 2020-10-15, 01:05
Only reason I would use XP64 is because I have a pre-activated copy, so wouldn't get pestered about having a dodgy copy. I don't have a pre-activated 7, and am unsure what happens if it's not registered and activated, now that there is no support available. Going to find out soon though 😀
