Dear Maintainer, this seems related to the ATA_DMA=y configuration. With a seabios package built with ATA_DMA=n, a directory listing of the install cdrom is possible again.
Also this setting seems to be introduced just with seabios
package version 1.12.0-1.
A google search returned following information, that
looks discussing the same issue, also about FreeDOS:

Kind regards,
