(11). FDC1 Connector
This 34-pin connector is called the “ floppy disk
drive connector ”. You can connect a 360K, 5.25”,
1.2M, 5.25”, 720K, 3.5’’, 1.44M, 3.5” or 2.88M,
3.5” floppy disk drive.
A floppy disk drive ribbon cable has 34 wires and
two connectors to provide the connection of two
floppy disk drives. After connecting the single end
to the FDD1, connect the two connectors on the
other end to the floppy disk drives. In general,
people only install one floppy disk drive on their
computer system.
Note
A red mark on a wire typically designates the location of pin 1. You need to align the wire pin 1 to the
FDC1 connector pin 1, then insert the wire connector into the FDC1 connector.
(12). IDE1, IDE2, IDE3 and IDE4 Connectors
This motherboard provides two IDE ports (IDE1 &
IDE2) to connect up to four IDE devices in Ultra
DMA 100 mode by Ultra DMA 66 ribbon cables.
Each cable has 40-pin 80-conductor and three
connectors, providing two hard drive connections
with the motherboard. Connect the single end (blue
connector) at the longer length of ribbon cable to the
IDE port on motherboard, and the other two ends
(gray and black connector) at the shorter length of
the ribbon cable to the connectors on hard drives.
NV7-133R’s built-in HighPoint HPT 372 chipset
gives you the capability to support Ultra DMA 133.
It provides two IDE channels (IDE3 & IDE4) that
also support Ultra DMA 133 specifications, and it
allows for four additional IDE devices in your computer system. Especially, if you want to connect two or
four HDDs to get RAID functions, it is very convenient for you to install the HDDs to IDE3 and IDE4.
See the Chapter 4 for detailed information about RAID settings.
If you want to connect two hard drives together through one IDE channel, you must configure the second
drive to Slave mode after the first Master drive. Please refer to the HDD documentation for jumper
settings. The first drive connected to IDE1 is usually referred to as “
Primary Master ”, and the second
drive as “ Primary Slave ”. The first drive connected to IDE2 is referred to as “ Secondary Master ” and
the second drive as “
Secondary Slave
”.
Keep away from connecting one legacy slow speed device, like CD-ROM, together with another hard
drive on the same IDE channel, this will decrease your integral system performance.
