These documents were released by Eyetech Group to address certain hardware bugs
of the AmigaOne XE and how to fix them or work around them.

A1XE-USB-XE-fix - "Proceedures for correcting the USB ‘reconnect
fault’ on the A1-XE boards" 
Documents the issue of hotswapping USB devices and where to add resistors to fix
them.


A1XE-UDMA-XE-fix - "Proceedures for correcting the UDMA timeout using the
on-board VIA UDMA-IDE
controller on the A1-XE motherboards when using OS4" 
Documents the issue of not being able to use DMA transfers using the onboard VIA
ATA/IDE controller and a inrreversable motherboard modification to fix it -
HIGHLY UNRECOMMENDED as this procedure causes other hardware issues such as not
being able to use a Radeon HD graphics card. Use a Silicon Image SiI 0680 ATA
controller instead.
