I'm trying to get Windows 7 working on a Supermicro P3TDL3 with a pair of Tualatin 1.4GHz and 4GB RAM (3.5GB usable).
The current system runs DOS and XP just fine (for anything before requiring SSE2), but with Windows 7, while it works performance-wise, I'm not sure it's the board or the OS having problems.
Some did try running Windows 7 on such or similar systems before, though I have not heard of anything referring to crashes.
The LSI SAS3041XL-S PCI-X SATA/SAS cards (SAS1064) which I use for hard drives and optical drive are natively supported under Windows 7. They offer full SATA2 (300MB/s) performance, and could outperform even the onboard SATA on some later chipsets. It can also correctly configure the DVD boot options to suit Windows 7 installation discs (using P3TDL3's onboard IDE for DVD the Windows 7 disc would not boot and boots the hard drives instead). Honestly, this is one plus for those cards, as with these, the OS installation progressed as fast as that on a modern machine.
I'm using a GeForce GT 610 PCI which works as intended under XP, but for some reason, I'm having problems with driver installations under Windows 7... notably the DBInstaller crashes (exception 0xe0e00104 in the log). However, I've not heard of any requirement for SSE2 with nVidia drivers... and that under Windows XP, even the latest drivers would work without issues.
Drivers up to R319 beta (320.00) since initial support driver (301.42) can be installed, but I cannot open the control panel (after some updates, it went as far as giving a NVidia User Experience crash whenever it's invoked, including right-click menu on the desktop, making right clicking on the desktop useless). I don't prefer using XP drivers under Windows 7 given some features would not be available if doing so.
Also, WinSAT cannot be performed at all (showing nothing for a few seconds then exits with failure, no apparent errors from what the logs said), with or without nVidia drivers installed, making it not possible to enable Aero in the future (apparently DWM also crashes).
So I'm not sure whether there are some aspects in Windows 7 implicitly requires SSE2 or better (and give crashes for SSE2-incapable CPUs), be it since the very beginning or recently, as not all programs detect SSE2 support prior to execution (before or after such requirements) and would happily crash when they find out the CPU couldn't perform what they expected... I have not heard of such, given that few actually tried installing it on such hardware and most software back then have not required SSE2 when Windows 7 just came out. It may be more about how well ServerWorks chipsets can cope with other software... given there are very limited information about it (so limited that even chipset-specific stuffs like UMBPCI couldn't support it), yet Windows 7 does have drivers for such.
Aside from that, I don't have issues with other drivers so far, like the unofficial Vista driver for Aureal SQ2500 (works with Win7 even using optical), and the onboard Intel NIC (apparently Intel NICs are well supported almost everywhere compared to other manufacturers).
Guess a lot is still needed for using Windows 7 on such systems...
