The corresponding driver is installed in the file CONFIG.SYS by the following command:

device=[d:][path]SDxxx.SYS [remark][/bb][remark][/llll][remark][/pp]

The particular parameters have the following function:

[c:][path] drive and path specification with driver SDxxx.SYS, whereby xxx

indicates the memory type being used for the silicon disk. The three

described drivers SDRAM, SDROM and SDPEROM are available.

[remark] optional text excluded the slash "/" and entry key

/bb base address of the silicon disk (step ratio = 64 kByte)

(e.g. /C0 corresponds to the physical start address C00000hex)

/llll capacity of the silicon disk (step ratio = 1 KByte)

(e.g. /256 corresponds to a disk capacity of 256 KByte = 262144 Byte)

/pp parameter for SDPEROM.SYS: block size of PEROMS

64 for AT29MC010 module

128 for AT29C010 and for AT29MC040 module

256 for AT29MC040 module

Examples:

Chip Silicon Disk with 1MB EPROM:

DEVICE = \DEVICE\sdrom.sys base address=/c0 size=/1024

Explanation: The driver is in the subdirectory "DEVICE" on the boot drive. The silicon disk

consists of a read-only memory. Therefore, the driver SDROM.SYS is taken. The

base address of the silicon disk lies at C00000H. The silicon disk has a capacity of

256 KByte.

Chip Silicon Disk with 256KB SRAM:

DEVICE = \DEVICE\sdram.sys base address=/c0 size=/256

Explanation: The driver is in the subdirectory "DEVICE" on the boot drive. The silicon disk

consists of a write-only memory. Therfore, the driver SDRAM.SYS is taken. The

base address of the silicon disk lies at C00000H. The silicon disk has a capacity of

1024 KByte = 1 MByte
