Linux on old hppa c3000, dvd ide found..但不可用

  • 772

我在 HPPA C3000 上运行 Debian SID，HPPA C3000 是 HP 的一个非常古老的工作站。我有这个问题，ide cd-drom 驱动器似乎可以识别，但没有创建设备。dvd 被识别：

dmesg |grep -i dvd
[   34.066904] ata1.00: ATAPI: ATAPI   DVD+RW 4X4X12, B1GY, max UDMA/33

但没有创建设备！

cdrecord -scanbus
wodim: No such file or directory. 
Cannot open SCSI driver!
For possible targets try 'wodim --devices' or 'wodim -scanbus'.
For possible transport specifiers try 'wodim dev=help'.
For IDE/ATAPI devices configuration, see the file README.ATAPI.setup from
the wodim documentation.

我尝试 modbprobe pata_legacy 并且机器进入内核恐慌。

编辑1：检查 dmesg 我看到错误..

    找到解决方案。c3000 手册（主要是指 HPUX，而不是 Linux）报告为 cd-rom ide 设置“电缆选择”。但是，如果我设置为电缆选择，则在第一次发布时报告错误并且不起作用。我把它设置为主人和..

    cd-info 和 lsblk 报告驱动器。所以找到了解决方案。
