Newsgroups: comp.sys.apple Subject: Re: Re: ProDOS block 0 Message-ID: <8908060943.AA05540@uxa.cso.uiuc.edu> Date: 6 Aug 89 09:43:50 GMT Organization: The Internet Lines: 34 Sorry, I spoke too soon, i.e. before implementing your suggestion: My block 0 now looks like this: 00:01 4C BA FA or 01 4C FA BA : JMP FABA The disk rattles, spins, and doesn't stop. It apparently reads in block 0, but after this, it just keeps spinning the disk. Taking the disk out doesn't stop it or make the drive rattle for lack of data. It actually acts like the old Disk IIs, except it won't boot a newly inserted disk. I then tried my old code: 00:01 A5 05 8F E8 02 E1 4C A6 FA or 01 : A5 05 : LDA #05 8F E8 02 E1 : STA E102E8 4C A6 FA : JMP FAA6 This does what it's supposed to, however when FAA6 is called, the Battery- RAM is rewritten into the RAM buffer, killing my hack. So it just boots up the default drive (6) again > infinite boot. Why doesn't something this simple work? Sheesh, it's just my night...er, morning... Ken. krb20699@uxa.cso.uiuc.edu {Internet}
