Microdrive detection timeout

[skiselev]

This issue is probably a bit geeky (but isn't it all?!). I tried using a Hitachi 6 GB Microdrive, which is an actual spinning hard drive in a CompactFlash form factor. It appears that RomWBW doesn't give it enough time to "spin" on boot. So I am getting a "BUSY TIMEOUT" error. When the system is restarted from the RomWBW boot loader it properly detects the disk
