I think about switching from ATA to SATA, now that i realized that there are SATA150 DVD burner from LG
I also looked up some HD's from Seagate (60? up), but am unsure about the compatibility.
1. As i understand it the Sil3112/3512 and SATA3114 are SATA150 only? Can i use SATA300 HD's on them? (Of course loosing the high performance)
2. Can i boot from SATA drives as i can with ATA?
3. Whats the speed difference, is it worth it?
Thanks

Which leads me to the question (as i don't know much about SATA) if i can use four drives with the 3112 (as the sil0680 can, or di i have to use the four port 3114 to be able to plug three (or more) devices in?

U-Boot supports the sii3112, it doesn't support the sii3114. I don't know if the sii3512 is supported or not, it's not mentioned in the docs. Booting in AmigaOS4 works with all 3 of course, but if you use a controller not supported by U-Boot AmigaOS4 has to be loaded from something else, for example the PATA HD you are currently using. If you are currently using a sii0680 and need the PCI slot for the SATA controller you can connect the HD to the motherboard VIA controller instead.

There is no speed difference. Like with the PATA sii0680 and it8212 controllers the max. theoretical speed is 133 MB/s (UDMA6), and since you'll use it in a PCI33 slot it can't be faster anyway. The motherboard VIA PATA controller only supports up to UDMA5 (100 MB/s), but that doesn't make any practical difference either, there are no HDs which are that fast, only reading/writing from/to the drive caches, not the disk itself, could be a little bit faster with a PCI UDMA6 controller compared to the motherboard UDMA5 one.
You can connect 2 drives to a sii3112 and sii3512, 4 drives to a sii3114.
Thanks a lot, joerg, that pretty much answered all my questions, so i'll save my honey for some other special bee

IIRC out latest U-Boot 1.2.0 build does support the sii3114. I'd have to check the source code, but I am pretty sure it does.

So the best setup when disk access is crucial is to have a pic gfx card in 33MHz slot and HD controller in the 66 MHz slot Hmmm....

I have such a setup now, and HDs which are fast enough to make a difference. Sequential reading of 250 MB in 64 KB chunks using the device (not through a file system) from identical HDs using UDMA5: sii3112, PCI33 slot: 5.955 sec., 41.982 MB/sec. sii3114, PCI66 slot: 3.204 sec., 78.017 MB/sec.
Unless there is a difference between the 3112 and 3114 or the drivers, I didn't test the 3112 in the PCI66 slot, using the PCI66 slot instead of a PCI33 one makes a much larger difference than it should.
But it's a quite useless test, there are no seeks and it's reading everything to the same 64 KB buffer without using the data (just using 2 64 KB buffers instead of one and alternate both drops the speeds to 37 and 63 MB/sec. already). On normal usage, through a file system, actually using the data read, etc., the difference is probably minimal.
I have just tried to put in a LG DVD burner and no matter what I do it is not seen by the OS, no CD0: shows up at all. Any help appreciated.
If the DVD burner has a higher unit number than the last HD start MediaToolBox and save the changes it should detect (it's no longer the last unit) to the last HD.
I didn't know the sii cards could be used in a PCI66 slot.
Check the card, PCI cards compatible to both PCI33 and PCI66 have 2 holes in the connector. You have to check it youself since the pin is missing in the PCI66 slot of the A1-XE, they used PCI33 ones for all 4 PCI slots and you can put a PIC33-only card in the PCI66 slot, but doing that would be a very bad idea since AFAIK PCI33 and PCI66 use different voltages.

Ok, I opened up MediaToolbox, klicked on sii3114 and all that shows up is my HD.
Back in the old days all I would have to do is load CD0 into a text editor and change the Device and unit number. I am at a lost of what to do next. The DVD burner works fine under Vista.

It's not required on AmigaOS4 since it's done automatically by diskboot.kmod. Being able to edit a mountlist/DOSDriver file wouldn't help at all, if it's not shown by MediaToolBox the device driver didn't find it and CDFileSystem can't use it either, no matter if an automatic or a manual mountlist is used. Check your U-Boot sii3114 variables, maybe explicitly set the unit of the DVD Burner to CD/DVD instead of auto detection. If that doesn't help set the OS4 command line to "debuglevel=1" (or set the sii3114_verbose U-Boot variable, but I'm not sure about the name, check the docs), do a cold reboot and post the debug output from the sii3114 driver, you can get it with C:DumpDebugBuffer.
