Summary Regresssion 09479: lb186: Unable to boot a floppy disk
Description This system is marked as working.

According to the manual, the system waits for a boot disk and will then boot without requiring further intervention.

There's no software list, so I tried my only LB186 disk and it didn't boot. The system is also supposed to be able to use standard IBMPC boot disks, so I tried a number of them, without luck.
Steps To Reproduce >mame lb186 -flop1 e:\data\pc\ok\freedos360k_1_20061014.img

Cursor flashes faster but nothing else happens.

In the debugger, nothing is loaded into memory, and code execution stays in the BIOS.

Tried a bunch of pc disks, MAME rejected most of them, however 360k ones were accepted, but none did anything.
Additional Information Tested in 0.277, the system works there, able to boot one disk "freedos360k_1_20061014.img". Seems quite picky; other disks that work in pc's get the "Non-system disk or disk error" response instead.

In 0.288, there's no messages, doesn't seem to read the disk at all.
