安腾机器默认的console是VGAconsole,甚至在EFI中,已设定了serial console。
为了设定serial console,必须将console= 参数传递给kernel。做法有两种:
1. manual boot option
fs0:>elilo linux "console=ttyS0"
2.automatic via elilo.conf
在elilo.conf文件中,加入append=console="ttyS0"一行
在EFI Console-In/Out table中,必须选择一个UART. PNP0501表示Serial A 或Serial 1 built-in UART,而HWP0002表示MP卡上的console UART.
UARTs编号规则如下:
rx2600/zx6000 without a MP(built-in UART selected for Console-In/Out)
ttyS0:serial [A|1]
ttyS1:serial [B|2]
rx2600/zx6000 with a MP(built-in UART selected for Console-In/Out)
ttyS0:serial [A|1]
ttyS1:serial [B|2]
ttyS2:UPS/AUX Port
ttyS3:Console Port
ttyS4:Modem/Remote Port
ttyS5:Local Session
rx2600/zx6000 with a MP(MP console selected for Console-In/Out)
ttyS0: Console Port
ttyS1: serial [A|1]
ttyS2: serial [B|2]
ttyS3: UPS/AUX Port
ttyS4:Modem/Remote Port
ttyS5:Local Session
rx5670(MP console selected for Console-In/Out)
ttyS0: Console Port
ttyS1: UPS/AUX Port
ttyS2:Modem/Remote Port
ttyS3:Local Session
