Re: ACPI and Linksys 10/100 PC Card (ed1)

Hi Matt,

Just a quick note.  It seems that the recent work done on the ACPI code 
has fixed my problem.  The boot process still 'pauses' when it reaches 
my CDRW drive, but it continues and works fine!

I just did a fresh install from the snapshot iso: 2004-08-08 and it 
booted perfectly from the CD.

Thanks to all who did the hard work! :D

Kind regards,

Henry
