Yes, this does require 52kB space in total. Where the maps occur are more to do with OLDCARD than with the ray driver. I'm going to have go at tidying up some of the pccardd/OLDCARD memory interactions and will try and get this fixed. The performance hit of continually re-mapping the memory areas is really high. I haven't forgotten about the bank switching idea we discussed a couple of weeks ago, but I have concentrated on the ping times. > Greg > -- > Finger grog@lemis.com for PGP public key > See complete headers for address and phone numbers Duncan --- ________________________________________________________________________ Duncan Barclay | God smiles upon the little children, dmlb@dmlb.org | the alcoholics, and the permanently stoned. dmlb@freebsd.org| Steven King To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe cvs-all" in the body of the message
