Startup-slowdown is now implemented. It's a logic update that can only be installed here. If you have trouble with a harddrive not being recognized, please send your card back for an update to Vesalia.
During the start phase, I am now limiting mainboard access to half the normal chipram access speed, regardless of "express" functionality (which includes kickstart rom and IDE controller). Startup now feels a second slower (not actually measured..), which is considerably slower than any version of the ACA1230 (28, 42 or 56MHz are all faster than that).
Speed in normal operation is not affected by this logic update.
