TIMEOUT_MAXIMUM			EQU		255			; We would actually want 31 seconds here but I don't think there are so slow drives


; ATA specs say that in standby mode time to respond could be as long as 30 seconds
; Note that some low-power drives (like Toshiba 1,8" HDD) have power management enabled by default
; TODO: It might be better to define timeouts in IDEVARS (in ROMVARS) or in DPT. Having even a single bit in DPT means
; we could adjust timeouts on runtime when enabling or disabling power management.
