If a PC Card memory device is recognized, the pcram device driver is automatically loaded, the physical address allocated, and special files created (if they don't already exist).
The Solaris pcmem driver is not capable of handling "combo" memory cards with multiple types of memory on them (for example, combined SRAM and nonvolatile FLASH). Inserting such a card into a system running the Solaris software may cause a system panic.
Because the PC Card memory device is designed as a pseudo-floppy diskette type, the only utility that can be used for formatting is fdformat(1).
