 Frequently Asked Questions

B-5

(for example, 5-1-1-1 compares with EDO 5-2-2-2).  The SDRAM comes in
64-bit 168-pin DIMM (Dual-in-line Memory Module) and operates at 3.3V.
Note that some old DIMMs are made by FPM/EDO and only operate at 5V.
Do not confuse them with SDRAM DIMM.  AOpen is the first company to
support dual-SDRAM DIMMs onboard (AP5V), from Q1 1996.

Q: Can SDRAM DIMM work together with FPM/EDO SIMM?

A: The FPM/EDO operate at 5V while SDRAM operates at 3.3V.  The current

MB design provides different power to DIMM and SIMM but connects the
data bus together.  If you combine SIMM and DIMM, the system will still
work fine; however, only temporarily.  After a few months, the SDRAM 3.3V
data input will be damaged by 5V FPM/EDO data output line.  Therefore, we
strongly NOT recommend DIMM and SIMM combined together.  There is one
exception, if your SDRAM supports 5V tolerance (such as TI or Samsung),
which accepts 5V signal at 3.3V operating power, you can combine them.

Q:  What is Bus Master IDE (DMA mode)?

A: The traditional PIO (Programmable I/O) IDE require s the CPU to involve in

all the activities of the IDE access including waiting for the mechanical
events.  To reduce the workload of the CPU, the bus master IDE device
transfers data from/to memory without interrupting CPU,  and releases CPU
to operate concurrently while data is transferring between memory and IDE
device.  You need the bus master IDE driver and the bus master IDE HDD to
support bus master IDE mode.  Note that it is different with master/slave
mode of the IDE device connection.  For more details, refer to section 2.3
"Connectors".

Q: What is the Ultra DMA/33?

A: This is the new specification to improve IDE HDD data transfer rate.  Unlike

traditional PIO mode, which only uses the rising edge of IDE command
signal to transfer data, the DMA/33 uses both rising edge and falling edge.
Hence, the data transfer rate is double of the PIO mode 4 or DMA mode 2.
(16.6MB/s x2 = 33MB/s).
