Has anyone gotten PC Ditto 3.0 (Software version) to boot from a hard disk with an ICD Boot also? I tried setting the third through (nth?) bytes with $90 IBM 3.3, but apparently DOS looks for more before deciding that the disk is bootable. Any help appreciated... -- Greg

Oh yeah, I did format /s c: before hand from PC Ditto, then told the HDUTIL program to set c as boot, but it overwrites much of the boot sector with it's stuff. -- Greg

The DOCs with PC_Ditto (II) describe the problem and a fix. The problem: MS-dos and PC_ditto are very fussy about what the see in the boot block of the C: (and other) drives. (THIS IS NOT SECTOR 0). Some formatters and Partitioner do not put the right stuff their. HDX from Atari is screws this stuff up. This was the root of the floppy incompatibility problems; but few people exchange Hard disks witha PC. It looks like ICD now does not put the right magic there. If the ICD editer is a smart as Supras, display the boot for C: and make sure that there are 2 not 20 fats, and the media bytes is f8. Avant-Garde now supplies a fixup program with PC-ditto II, but its needed for I also. Howard C. Johnson ATT Bell Labs att!lzsc!hcj hcj@lzsc.att.com

If it is already set to autoboot, then copy all files off of the drive because you are about to erase everything. Second, boot up pcditto and issue the command FORMAT C: /S This will logically format the disk and write the system and boot sectors onto the partition sector (0). When finished do the <CTL><ALT><DEL> thing and go back to the title screen. Reboot the IBM mode from the hard drive this time to see if that works at least. When you have the IBM system booting off the hard drive then go back to ST mode. Finally copy your ICDBOOT.SYS back to drive C and now boot the ST to make sure that works. Then run pcditto again and make sure that works. If I remember correctly, that is how I did it and it works on my system. Once you can boot off both systems then you can put all your files back on drive C and continue as normal. Oh, one thing...You cannot have a disk in drive A: when booting from the hard drive in IBM mode, the program will lock up. However, after the boot cycle is over, it is wise to put a disk in drive A: and access it, otherwise the motor will keep running (my drive light is not on, but the motor is running, this shuts it off).
