Leading to the following output from a freshly powered on E3:

Amstrad Delta - PBL V4.9 Build:1311 Assert Debug ICE
PBL 32MB NAND
0MB.-->MEMv01.00.002,CopyLim=00220000h,CodeEnd=01400000h-->PBL......1MB.......2MB*

!LDR started.
Looking for NAND.
Enabling CE.
Resetting chip.
Reading chip ID (send ReadID).
Reading chip ID (send addr 0).
Reading chip ID (manufacturer).
Reading chip ID (id).
Disabling CE.
Found Tosh NAND.
