CDROM not working: CDROM not High Sierra or ISO-9660 format

[zompiexx]

Hi,

Following a recent update, I am no longer able to access the CDROM in the AO486 core. The drivers are loading (in MS DOS 6.22), but when I attempt to access the drive, I get the following error:

CDROM not High Sierra or ISO-9660 format reading drive E
Abort, Retry, Fail?

This was working until recently. I have tried a number of different ISO images, and have the same issue.

Please can you investigate.

Thanks in advance,

Andy
