;-------------------------------
|
|
; This is a map of how much we care about each sector
|
|
; on the disk. Each byte is one sector, arranged in
|
|
; increasing logical sector order from T00,S00 to T22,S0F.
|
|
; Some sectors have their own individual labels just for
|
|
; convenience.
|
|
; e.g. LDA #$80
|
|
; STA T00S0A
|
|
; will mark T00,S0A as optional
|
|
;
|
|
; Possible values for each sector:
|
|
; 00 = ignore this sector (don't even read it)
|
|
; 80 = sector is optional -- read, but ignore any errors
|
|
; FE = sector is required, and switch to the built-in RWTS
|
|
; after reading it (if we haven't already)
|
|
; $FF = sector is required -- read, and any error is fatal
|
|
; (this is the default value for all sectors)
