Subject: [PATCH] Workaround bogus CF cards
Date: 04 May 2003 12:14:37 +0200 [thread overview]
Message-ID: <1052043277.4107.76.camel@gaston> (raw)
Hi !
I had a problem with an "APACER" Compact Flash card. It seems that
beast is allergic to WIN_READ_NATIVE_MAX.
I hacked this workaround that appear to work fine
