New Revision: 220126
URL: http://svn.freebsd.org/changeset/base/220126
Log:
- Enable an extra debugging bootverbose printf when probing ISA PNP cards
listing each card as it is found on non-PC98 (PC98 already had this).
- Increase the length of the DELAY() used before timing out while reading
PNP resource data.
