> driver for IDE controllers using the SMC 73661(2) chipset
> Enables use of 2.88 floppies on system without bios support
> Enables use of 3rd and 4th floppies on 4-floppy controllers
The 4FDC.com program usage:
4FDC [/a:type] [/b:type] [/c:type] [/d:type]
The drive type "TYPE" may be one of the followings:
TYPE := 0 for NONE drive
:= 3[60K] for 360K drive
:= 7[20K] for 720K drive
:= 12[20K] for 1.2M drive
:= 14[40K] for 1.44M drive
:= 2[880K] for 2.88M drive
The braket [ ] are used for characters that can be omited.
To install 4 FDD drivers, you also need to setup CONFIG.SYS with following
settings:
device=c:\dos\driver.sys /d:?/f:?/s:?/t:?/h:?
which:
d:0 => fdd driver 1
d:1 => fdd driver 2
d:2 => fdd driver 3
d:3 => fdd driver 4
f:0 => below 360KB/5.25"
f:1 => 1.2MB/5.25"
f:2 => 720KB/3.5"
f:7 => 1.44MB/3.5"
f:9 => 2.88MB/3.5"
s:9 => 360KB or 720KB
s:15 => 1.2MB
s:18 => 1.44MB or 2.88MB
t:40 => 360KB
t:80 => 1.2MB or 1.44MB
t:160 => 2.88MB
h:2 => 2 heads
Example:
If the DOS command "driver.sys" in the "c:\dos\" sub-directory
and you would like to install:
FDD 1 for 1.2MB/5.25"
FDD 2 for 1.44MB/3.5"
FDD 3 for 2.88MB/3.5"
FDD 4 for 1.2MB/5.25"
Then, in the CONFIG.SYS file, you should to setup as follows:
device=c:\dos\driver.sys /d:0/f:1/s:15/t:80/h:2
device=c:\dos\driver.sys /d:1/f:7/s:18/t:80/h:2
device=c:\dos\driver.sys /d:2/f:9/s:18/t:160/h:2
device=c:\dos\driver.sys /d:3/f:1/s:15/t:80/h:2
also, you should to add:
4FDC /a:12/b:14/c:2/d:12
into the AUTOEXEC.BAT file for auto setting while PC booting.
EMM386 PARAMETER NOTE:
If you shall use emm386.exe from DOS 5.0 , please add the following option.
/D=32
The default dos DMA buffer = 16 KB is too small for 4M driver.
The track size of 4M drive is equal to 36 sectors (18K).
