yes, it comes from UDMA2.SYS, it does a series of initialisation tests (read
spead for example, and VDS).

I don't know behaviour when booting to MSDOS on harddisk, only Isolinux
--> A: and Isolinux --> Memdisk --> Disk image

Most likely the UDMA2 driver ends up running into the CD-ROM eventually, 
and croaking because it's not a hard disk.  It should examine the EDD 
information a bit closer; it'd find that it's marked accordingly.
