Format of diskette parameter table: Offset Size Description ) 00h BYTE first specify byte bits 7-4: step rate (Fh=2ms,Eh=4ms,Dh=6ms,etc.) bits 3-0: head unload time (0Fh = 240 ms) 01h BYTE second specify byte bits 7-1: head load time (01h = 4 ms) bit 0: non-DMA mode (always 0) Note: The DOS boot sector sets the head load time to 15ms, however, one should retry the operation on failure 02h BYTE delay until motor turned off (in clock ticks) 03h BYTE bytes per sector (00h = 128, 01h = 256, 02h = 512, 03h = 1024) 04h BYTE sectors per track (maximum if different for different tracks) 05h BYTE length of gap between sectors (2Ah for 5.25", 1Bh for 3.5") 06h BYTE data length (ignored if bytes-per-sector field nonzero) 07h BYTE gap length when formatting (50h for 5.25", 6Ch for 3.5") 08h BYTE format filler byte (default F6h) 09h BYTE head settle time in milliseconds 0Ah BYTE motor start time in 1/8 seconds ---IBM SurePath BIOS--- 0Bh BYTE maximum track number 0Ch BYTE data transfer rate 0Dh BYTE drive type in CMOS SeeAlso: #03226 at INT 4D/AH=09h
