旧hppa c3000上的Linux，dvd ide found..but不可否认

Question

我在HPPA C3000上运行Debian，这是一个来自HP的非常老的工作站。我有这个问题，ide光盘驱动器似乎被识别了，但是没有创建任何设备.dvd被确认为：

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

但是没有设备被创造出来！

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.

我试图对pata_legacy和机器进行修改，使其陷入内核恐慌。

edit1:检查dmesg我看到错误..。

我的部队失败了吗？

找到解决办法了。c3000手册(主要指HPUX，而不是Linux)报告为cd-rom设置“线缆选择”。但是，如果我设置为电缆-选择报告错误的第一篇文章，并没有工作。我把它设为主人..。

光盘和lsblk报告驱动器。所以找到了解决办法。
