This is version of Findbad that will operate correctly on the Osborne Executive. This was not done by rewriting findbad for CP/M Plus, but by installing a RSX in the CP/M 2.2 version of Findbad. This simple procedure will work on many CP/M programs that previously would not work on CP/M Plus. When using this version of findbad, the first difference you will notice is that the message BIOS ver 2.21 ACTIVE will be displayed. This is the RSX that will keep the program from bombing. The next difference you will see is that if a bad sector is found, a CP/M plus error message will be display saying: BIOS error reading drive B: crc-error Retry this operation (Y or N)? Just answer N for No, and findbad will lockout the sector by creating a file [UNUSED].BAD Wish I could take credit for this, but the credit goes to the author of BIOS2-21. BIOS2-21 is based on a program that first appeared in Dr. Dobbs, and was corrected by Monroe Chasson of the New York Osborne Users Group. This is just one application of his program, and you should get BIOS2-21.LBR if you want to use the program further. Thanks Monroe. Ron Forsythe SYSOP FOG #18 m further. .
