Re: [ECOS] PC boot image for 720k FDD

[Vlastimil Masek <rur at altavista dot com>]

Thank you all very much for the advises! My problem was solved by changing 	"sectorsPerTrack = 9 /*18*/"  in "../hal/i386/pc/<version>/include/platform.inc". 

The need for 720K FDD support is due to I am using Japanese PC (Toshiba Dynabook 386/20 J-3100) that has 1.2M FDD. This FDD, however, can also read 720K floppies that can be easily produced on majority of available PCs.

Thanks a lot again!
