The size of the emulated drive depends on the size and number of
the chips you install. For example, if you install three 512 KB chips,
you will have 3 x 512 KB = 1.5 MB, equivalent to a 1.44 MB floppy.
The following table shows the memory chips you will need to
emulate 360 KB, 720 KB, 1.2 KB and 1.44 floppy drives.
You will need to set jumpers J31 and J30 to match the type (Flash or
ROM) and size (128 KB or 512 KB) of the devices you use. All the
devices must be the same type and size.
EPROM 1.44 MB (default)
The following table shows the size and number of devices you will
need for each size emulated disk. It also shows the corresponding
settings of jumpers J31 (Flash/ROM) and J30 (size 128 KB/512 KB).

As previously mentioned, before you use the SSD you have to
enable it. This is done via the BIOS and a single three pin jumper
(J29). The jumper overrides the BIOS, even if you set the SSD to
enable in BIOS, it will not work unless the jumper is in place as the
table shows below:
