Should NOT be a question of "changing their baby", since if the VirtualBox people had done a PROPER job of "emulation", neither they nor I would need to worry about changes. However, I have now seen that VirtualBox (A) "times out" if UIDE tests for SATA/IDE drives using their ICH9 logic, (B) doesn't post a diskette "media change" flag, and God-knows what else!! "Backward compatibility" must be something they never have heard of, same as Microsoft proves with each new issue of "Vista" or whatever it is called today! Be-advised that UIDE does not have logic to "flush" its cache for specific drives; it can only flush its ENTIRE cache when a diskette/CD/DVD changes, or when the user issues a "CC" command (clear cache) to my CC.COM program. "CC" issues a BIOS reset to all hard disks, useful if one wishes to verify data written to a disk. So, a "workaround" for you, if you must ever use multiple diskettes in VirtualBox with UIDE again, is to issue "CC" if your diskette must be changed. This will "flush" UIDE's cache and prevent the "same diskette" problem from occurring. Jack R.
