用唔用到 pci 硬件 , 要看 件 硬件有無 64bit driver
intel lan 卡 , 大路的 好多時 os 都 build in

唔該哂你....我想問pci 係咪133MB/s   咁gigabit 咪冇咁快

gigabit = 1G bits / sec = 1024M bits /sec = 128M Bytes / sec
pci 係 133M Bytes / sec

gigabit = 1G bits / sec = 1024M bits /sec = 128M Bytes / sec
pci 係 133M Bytes / sec

For telecom
unit = bit
10^3 = Kilo bit
10^6 = Mega bit
10^9 = Giga bit
gigabit = 10^9bps = 1Gbps = 1000Mbps = 125Mbps

For capacity such as memory/storage
unit = byte
2^10 = 1024B ~ 1KB = 8912 bit
2^20 = 1048576B ~= 1MB = 8388608 bit
2^30 = 1073741824B ~= 1GB = (1073741824 x 8) bit

Don't be confused between storage and data rate.

1000Mbps = 125Mbps

佢想話1000Mbps = 125MBps
