[BUG] Unsupported ATAPI CDROM commands (BE host)

[Randrianasulu]

Describe the bug
Using
507f3ee

I tried to boot auto-selected pmg3dt from rom

1998-08-12\ -\ 78FDB784\ -\ PowerMac\ G3\ Minitower\ (beige\ 266MHz)\ -\ 8.0-10.2.8\ -\ 128-768M.ROM

using universal 9.2.2 image as cdr_img and blank 100mb file as hdd.

Notably on big-endian Linux (Bonslack ppc32 -current)

But machine after making good chime and showing default 640*480 window seemingly hanged

I looked into log and noticed:

(  24.603s)          atapicdrom.cpp:341    ERR| .   AtapiCdrom@0: unsupported ATAPI command 0xAD   (  24.630s)          atapicdrom.cpp:341    ERR| .   AtapiCdrom@0: unsupported ATAPI command 0x55

(  78.260s)     atapibasedevice.cpp:218    ERR| .   AtapiCdrom@0: unsupported command 0xEC

Might be known limitation at this time ....

To Reproduce
Steps to reproduce the behavior:

1. clone this repo and build on big-endian ppc32 Linux host
2. get universal 9.2.2 mac os installer as isofile
3. try to boot pmg3t machine with this iso as cdr_img
4. See error (hang?)

Expected behavior
Installer boots as on qemu

BE DingusPPC should be compared with LE DingusPPC instead of QEMU. I'll try LE DingusPPC tomorrow. If it works, then that would be incentive enough to visit the BE PPC target again.
