FORM200 FSET200 FVER200 INIT.BAS INIT.BIN Form200 enables you to format discs to store 200k, though the actual capacity is 198k because 2k is taken up by the directory. As the format is alien to the Amstrad the disc parameter block must be patched to instruct the machine to access it. Consequently you need to use Fset200 to switch between the two formats. When the machine code from Fset200 has been poked into memory it is saved as init.bin. The program also writes and saves a small Basic program called init.bas which you need to run before using the 200k format. This loads init.bin and calls it. If you want to go back to standard format either CALL &9C76 or POKE &A8A8,0. It has become apparent that due to differences between disc drive mechanisms, some machines are not happy when pushed to extra performance. This causes the formatter to leave some sectors unformatted and will show up as problems when saving files. Fver200 is a simple routine to verify any disc newly formatted to 200k. You don't need to run the initialisation program first. Bad sectors show up as sad faces and you can abort the check by pressing Escape for a few seconds. Reformatting may cure the problem but some Amstrads may prove to be too unreliable. If you have two drives, try formatting on both. CWTA |
