No, actually this is WORSE behavior!

Starting about 1994 with V2.0C of the PCI BIOS, there is a request
drivers can issue which returns "PCI " in the CPU EDX-register, to
say that a V2.0C or later PCI BIOS is in fact present.   When UIDE
does a scan for UltraDMA controllers on the PCI bus, it expects to
find this "PCI " value.   If not, UIDE assumes NO such controllers
are present, meaning no hard-disks nor CD/DVD drives use UltraDMA!

Note in your UIDE messages above that your CD drive is now a "PIO"
device, not an "ATA-33" drive (33-MB UltraDMA speed) like before!

I do not use and do not want VirtualBox, after all its problems as
users have noted on this list!    However, if you do want to go on
using it, I would seriously "gripe" to Oracle (or its maintainers,
whoever they might be!) that if VirtualBox now FAILS a 17-year-old
test for the PCI BIOS, they need to DO SOMETHING about it, QUICK!
