That's certainly true: PCMCIA currently treats cards with no CIS as static RAM cards. Mostly because the issue has never really come up for me. I think that's a bit different from an unqualified "they do not work very well at all". Are linear flash cards with no CIS common? I'm only familiar with the Intel cards, which all seem to have a CIS. I've never had anyone ask about no-CIS flash card support, as far as I can remember. -- Dave To unsubscribe, send "unsubscribe mtd" to majordomo@imladris.demon.co.uk
