amithlon scsi and usb options

[fishy_fiz]

Although I think Winuae is an impressive program for what it does, I can never enjoy the amiga experience with it like I do with amithlon. Even with my customised super stripped down WinXP Pro install (boots in literally 5 seconds with next to no visible signs of Windows being involed) it just doesnt "feel" right and Windows still on occasion rears its ugly head in one way or another. Now this is fine for some people, but personally I like to have dedicated machines for specific purposes, and as far as a dedicated "amiga" pc goes, Winuae just doesnt do it for me despite having all the pieces of the puzzle well supported. Because of this Ive opted for good ol' trusty Amithlon once more (I think this is probably true of most people who have had luck with amithlon,... its hard to go back to another solution(in regards to "serious" amiga emulation)), however there are 2 main things I'd like to address before I do so and was hoping someone might be able to give me the answers Im after.
    Firstly, scsi drives...... I have a reasonably nice machine set aside for amithlon, c2d@3.86ghz, 1 gig ram, sblive, g400 matrox video card, etc. All fully supported and working well, however being that modern hardware support is minimal in amithlon I have no dma for hard drive access which makes things like watching videos, or other heavy i/o type stuff somewhat of an imperfect experience. The only workaround for this (unless I want to downgrade the hardware (my old athlon64 system I used to run amithlon on for example, despite being somewhat slower ran videos fine (well, dvd reolution rips at least))) is to use a scsi drive. The question I guess is, does anyone know what scsi cards are supported in amiga os, or amithlon ? I used an adaptec 2091 (iirc) in amithlon in an athlonxp system I used before the a64 even, but dont have it anymore, and I'll be darned if I can find another. Im sure there's others that are supported, but I have no idea what. Any info, thoughts, or suggestions here would be appreciated.
    The remaining issue isnt as essential, but still would be useful, and that is USB. Can anyone tell me please what the story with poseidon and amithlon is? Support was dropped if I recall in an earlyish version of amithlon. Is there any work around for this? Are there any USB pci cards that poseidon (or any other 68k usb stack) will support? Additionally, and slightly off topic, but now that poseidon is open source, is amithlon support once again possible?
    These few issues are stopping me having a 68k based Amiga system that Im perfectly content with. Sure, there's no custom chipset support, but 68k euae + setting up deftypes for adf images (ie. just double click an adf image and have it launch via euae) plays a large part in redeeming this, and there's other, slightly more elaborate methods to fill in any other custom chipset based voids (speed is great by the way in 68k euae under amithlon, although my experiments with it made me realise that breathless, while a nice engine, is a crap game:))
Anyway, thanks in advance.

Yes, because we all know how vital formatting is on a forum. Having said that though it reads fine, and is gramatically correct, and that's all that really matters. Someone who is willing to help rather than criticise pointless "flaws" (from thier own perspective) will overlook the fact that formatting on one persons monitor can be different than others. I decided to humor you anyway and make a few adjustments, but weirdly nothing changed, despite there now being a "last editted" note in the post.

All this aside though is anyone able to help me with the information Im after please ?

The thing with the custom chipset emulation though isnt so much the resources that are needed to emulate them, but with the fact that keeping timing in synch is necessary, and that's a big part of where the resources are "wasted". Additionally custom chipset emulation also removes the possibility of having direct access to the the hardware, which is a big part of why amithlon is faster and "feels" better. UAE and its variants need to emulate things like memory and so on as well, amithlon is more "native" to the hardware it runs on. I actually have my old athlon 64 3400+ machine that I used to run amithlon on, which all works nicely, its just somewhat slower than the core2duo machine I now have set aside for amithlon. It's only really for more intensive emulators (euae, dosbox, pctask, fpse, etc.), higher than dvd resolution videos, and compile speeds that the extra speed comes in handy, but being that these are some of the uses I have, it's good to have. 68k EUAE for example struggles to play aga games at full framerate with sound using the athlon64, whereas the core2duo machine happily runs aga games full speed, even those typically requiring upgraded 68k machines to run well.
As for AROS, Im a big fan, and have done quite a bit of development for it (aros archives has lots of my AROS work for example), and I have a dedicated machine for it as well, but part of the fun with amithlon for me is making a nice os3.x system (lots of resources to spare, so can add lots of extras over a default os3.9 install), as well as, as you mention the fact there's a lot of 68k software that doesnt exist for AROS. There is janus uae, and the intergration works pretty nicely for the most part, but theyre different systems, and I like to have a dedicated machine per OS (apart from Windows/linux/etc., where Im content to use virtual machines).
