Default: appl.bin
1541 Drive Enabled/Disabled the 1541 emulated drive
Default: Enabled
1541 Drive Bus ID This is the drive-id the emulated 1541 drive responds to. If
you combine multiple drives on the IEC bus, you should
always use different ID’s for each drive.
Default: 8
1541 ROM Select Selects the firmware (kernel) the emulated 1541 drive uses.
There are four possible choices, CBM 1541, 1541 C, 1541-II,
and Load from SD. If you select Load from SD, you need to
place a custom kernel for the drive in the ROOT of your SD
Card with the name 1541.rom The 1541 Ultimate will use that
kernel instead of the ones in the firmware.
Remark: CBM kernels are 16 KB. Other (third party) kernels
may have larger sizes. Kernels that exceed 16KB are currently
NOT supported, due to the fact that the 1541 Ultimate does
not have dynamic memory allocation.
Place the rom you wish to use in the root directory of your SD
card and rename it to ‘1541.rom’.
Default: 1541-II (Advise: CBM 1541)
1541 RAMBOard This option adds 16 KB extra ram to the drive if Enabled. Not
all software is compatible with the RAMBOard enhancement,
so if you don’t need it, leave it disabled.
Default: Disabled.
Load last mounted disk If set to Yes the 1541 Ultimate will auto mount the last
mounted D64 image on power-up (if present and in the same
location on the SD Card).
Default: No (Advise: Yes)
1541 Disk swap delay Delay time to report a disk change has happened.
Default: 100ms
IEC SDCard I/F This is the drive for direct access to the SD Card from your
