Hi Phil, That's a good suggestion, indeed, and I do have a free slot between the 2940U2W and the DS2416. I actually learned about this when working with LAW and the good old Multisound Monterey card. That thing picked up clock whine and noise unbelievably! Just so you know, though, I think something was hosed with the way in which the DS2416 driver went in. I un-installed the v1.30 DS2416 driver and dropped back to v1.21, which seems to be causing far fewer problems (full-amplitude spikes and the slow display problems even seems a bit better). The graphics still slow to a crawl if any kind of scroll in place settings are enabled, though. This bothers me a bit because on my brothers Mac, it's no problem -- even scrolling a Sample Edit window across two monitors seems to work fine on the Mac indicating to me that I should get a Mac -- just kidding. (Macs are wonderful machines, but I just can't afford to get into all that right now). Actually, I can now work this way OK, too, but I still get the occasional CPU too slow errors on occasion. I guess we'll soon see what LAW 4.1 brings. It sure is wonderful software in spite of it all, though. Thanks, Phil! -- Paul -----Original Message----- From: Phil Angus, Tech. Supp. Mgr, Hammer Dist.

Try and avoid the DSP2416 right next to the Adaptec (try and leave a slot free both sides. This is not always possible due to the number of cards, but first try and leave a gap between the component side of the Adaptec and the next card. I have seen problems with noise which caused a lot of real visible problems, and fixed when the (in this case) SB256 Live card was moved on to the next slot. This is probably even more critical when using the Ultra-2 40 mHz BUS as well as the ultra 20 mHz BUS. I have a very similar system, I have a RAID card as well but I have isolated the DSP as much as possible (I use an ISA network card) so I have 2940U2W + ATTO RAID (ultra-2) card, then a free slot, + 2416 on the PCI BUS + Matrox G200 AGP + the ISA card at the other far end. Although I occasionally get a problem similar to you, it isn't often enough to cause me a big problem, and like you I live in hope it will be ironed out in the next release. Hope this helps, let me know if it does. Phil Strike the 'any' key with the keyboard Phil
