aha1542=iobase[,buson,busof[,dmaspeed]]

The iobase for this card is usually, 0x130, 0x134, 0x230,

0x234, 0x330, and 0x334.

Some clone cards provide

other addresses as well. buson and busof specify the

time the card spends on and off the buss.

Default

values are 11 s on and 4 s off so that other cards get a

chance at the ISA buss. dmaspeed refers to the rate

at which the DMA transfers proceed. The default value

is 5 MB/s, although some cards allow setting up to

10 MB/s, but care should be taken to make sure that

the machine is up to the task.

aic7xxx=extended,no reset

A nonzero value for extended enables extended transla 

tion for large disks. A nonzero value for no reset tells

the card not to reset the card at boot up.

buslogic=

The only parameter that this argument accepts is the

iobase. The expected values are: 0x130, 0x134, 0x230,

0x234, 0x330, and 0x334.

tmc8xx=mem base,irq

The probe code for these Future Domain cards looks

for a BIOS on the card. If one is not found, or the

signature is not recognized, this card will go unrecog 

nized. Specifying the mem base address and the irq

in this argument will force recognition of the card. The

mem base address specifies the memory mapped I/O

region of the card and expects values: 0xc8000, 0xcc000,

0xce000, 0xdc000, 0xde000.
