Using Conventional Solid State Devices
You can use numerous memory types to implement a Conventional Solid State Disk. Depending on
the devices used, you may implement read/write, read-only, or write-once-read-many type drives.
Advantages of using the Conventional SSD include:
• Storage capacity up to 1 MB (EPROM only)
• Atmel Flash and NVRAM allow read/write capability using standard DOS file commands
Disadvantages of using the Conventional SSD include:
• Requires external utility program and device programmer to program 12 volt Flash, AMD
5-volt Flash, or EPROM.
• Limited memory size.
The following memory devices or their equivalents may be used for a Conventional SSD. Access
times for all devices must be 150 ns or less, and all devices
must be in 32-pin DIP packages.
• Atmel 29C010A, 29C020A or 29C040A
• +12 V Flash 28F010, 28F020
• +5 V Flash 29F010, 29F040
• SRAM 128Kx8, 512Kx8
• NOVRAM (Dallas Semiconductor DS1645Y, DS1650Y)
• EPROM (27C010, 27C020, 27C040, 27C080)
Installing a Conventional SSD using Atmel 5-volt-only Flash
To install an SSD using Atmel Flash, follow this procedure:
• Apply power to the cpuModule and run Setup.
• Set SSD socket 1 or 2 to the appropriate Atmel device type.
• Set SSD Window to a value which will not conflict with other hardware or software.
• Save your changes and exit Setup.
• Turn off the cpuModule.
• Install the memory device into the socket.
• Reboot the cpuModule. The SSD should appear as the next available drive in your
system.
• Format the SSD using the DOS format command.
• If you wish to boot from the SSD make it diskette A.
NOTE! The memory window selected for DOC must not be used by any other
program or hardware device. Make sure this window is not in use by
EMM386 or another memory manager, or an Ethernet card, PCMCIA
card, etc.
NOTE! If you wish to make the SSD bootable, you must format it using the /s
switch of the format command. Refer to your DOS manual for more in-
formation on format.
