I recently bought one of these to try out - google turns up almost nothing about this card, so I thought I'd document what I've learned about it.
1. It is bootable, at least on a Quadra 650/800, haven't tried any others yet. It will not find a bootable disk on it's own, but if you boot by some other means and use the Startup Disk control panel to select a disk connected to the SEII it will happily boot from that disk thereafter. It does this without any special drivers on either boot volume, at least on the disks I used.
2. It uses the same control panel and additional software as the Silicon Express IV, downloadable from the garden / repository, although this doesn't appear to be needed for basic functionality
3. It is a little over twice as fast as the onboard SCSI. SCSI Director 4.0 performance test with a SCSI2SD v6. shows peak R/W at 5811/4317 K/sec respectively, as opposed to 2838/1760 K/sec when connected to onboard SCSI.
If anyone has a manual or any reference material for the SEII specifically I would love to see it, as it seems only the SEIV manual exists online.
