Nope. News to me of its existence. Have any idea of the ub driver's size?
The trick is to get at least restore from USB storage able to be in the boot flash; I don't mind so much if we have to put TCP/IP and wireless modules into a partition on the regular flash. And if we can get it all to fit into less than 512K bytes (BIOS + Linux as bootloader), then we get to save $.3 to $.5, which over the number of units we're building, is more than small change. Thanks, - Jim

Have you looked at Pete Zaitcev's 'ub' driver instead of the full scsi stack ?

If you are usign CF it will also be possible to do a dedicated PIO CF driver a similar way to get rid of the IDE layer or libata. Wouldn't let you do CD tho.
