Summary: I'm baffled Message-ID: <550@arc.UUCP> Date: 8 Sep 89 01:00:33 GMT Reply-To: steve@arc.UUCP (Steve Savitzky) Distribution: usa Organization: Advansoft Research Corp, Santa Clara, CA Lines: 14 The title says it: I have some disks that were written on a non-DOS machine on a 96-tpi, MFM (i.e. normal density) drive. How do I tell the BIOS that the disks are 96-tpi? (I can read non-DOS, 48-tpi disks just fine, even on an AT; it looks like the AT's BIOS is double- stepping the head by default.) Has something been added to the "disk base" structure, or will I have to poke the driver directly, or what? -- Steve Savitzky | steve@arc.uucp | apple.com!arc!steve ADVANsoft Research Corp. | (408) 727-3357(w) / 294-6492(h) 4301 Great America Parkway | #include Santa Clara, CA 95054 | May the Source be with you!
