1) USB - as mentioned in my reply to [link|/forums/render/user?username=madodel|madodel], [link|/forums/render/content/show?contentid=92308|Post #92308], the USB controllers act like 1.1 controllers until a 2.0 device is plugged in.
2) mis-read the screen about the APM version. APM driver 10.070 was loaded, but the system's APM level is 0. It's 0 because the motherboard uses ACPI instead of APM. I googled up a [link|http://www.mail-archive.com/acpi-os2%40netlabs.org/|mailing list archive] started by Netlabs in November 2002. Don't think they're too far along yet as Netlab's site doesn't mention the mailing list anywhere.
As far as the eCS blob goes - now that the SCSI cable's plugged in the boot sequence lets me select "Legacy SCSI". However, it still has the long pause before it starts booting off SCSI. I even tried having SCSI as the only boot option :-/
