The SRAMDISK.SYS command must follow this syntax:<br />

device=d:\sramdisk.sys [disksize sectorsize entries]<br />

3<br />

where:<br />

disksize is the size of the RAM drive in kilobytes; specifies the<br />

amount of extended memory allocated for the drive. Type a<br />

number from 16 to 256; the default is 64. You can create<br />

multiple RAM drives if the sum of their disksizes is 256K or<br />

less.<br />

Note: You may be able to use more than 256K of extended<br />

memory for the RAM drive. For help, see the previous section,<br />

“Deciding How Much Memory to Use for RAM Drives.”<br />

sectorsize is the size of the disk sector in bytes. Type 128, 256, or 512;<br />

the default is 512. You can specify sectorsize only if you<br />

specify disksize.<br />

entries is the maximum number of files and directories you can<br />

create in the RAM drive. Type a number from 2 to 1024; the<br />

default is 64. You can specify entries only if you specify<br />

sectorsize and disksize.<br />

Here are sample SRAMDISK.SYS commands:<br />

• To create a 64K RAM drive:<br />

device=d:\sramdisk.sys<br />

• To create two 128K RAM drives:<br />

device=d:\sramdisk.sys 128<br />

device=d:\sramdisk.sys 128<br />

• To create a 256K RAM drive with 128-byte sectors and up to 16 entries<br />

in its root directory:<br />

device=d:\sramdisk.sys 256 128 16<br />

4. Load the reader’s CONFIG.SYS file on drive C using Auto-Loader, BFT, or<br />

MakeDisk and PutDisk, as described in “Learning How to Change the<br />

Contents of Drive C” earlier in this chapter.<br />
