Why my system becomes very slow or appears to hang when SRAM / FLASH card is accessed
Reason: After every mapping of memory window Microsoft PCMCIA.SYS driver waits card to set Ready signal. According to PC Card Standard this wait may last up to 5 sec. each time. This is so called an "active wait", i.e. during the wait time mouse not works and system appears to hang. If your card doesn't handle Ready signal properly it may result in several waiting - from user perspective system will hang.
Solution: There is no software work-around of this problem. You will need use another card or another type of the card.
