WDC(4) BSD Kernel Interfaces Manual WDC(4)NAME
wdc -- WD100x compatible hard disk controllers driver
SYNOPSIS
ISA and ISA plug'n'play controllers

wdc1 at isa? port 0x170 irq 15 flags 0x00

arm32
wdc0 at pioc? offset 0x01f0 irq 9
atari
wdc0 at mainbus0
amiga
wdc0 at mainbus0
DESCRIPTION
The wdc driver provides the interface with the hardware for the ata(4) driver. This driver supports IDE and EIDE controllers, as well as MFM,
RLL and ESDI on the ISA bus. PCI IDE controllers in legacy mode are also supported, but the pciide(4) driver may provide more functionality.
On the ISA front-end, the following flags are supported:
0x0001 Enables 32-bit I/O negotiation in the driver. This is known to cause problems with some motherboards.
0x0002 Don't probe for the second drive.
0x0004 Set WDC_CAPABILITY_ATA_NOSTREAM flag.
0x0008 Set WDC_CAPABILITY_ATAPI_NOSTREAM flag.

I have seen some misinformation regarding Unix file permissions. I will try to set the record straight. Take a look at this example of some output from ls:

sort -nr --key=1 ....
The output I get is:

Suppose I have a main() function with only one malloc statement allocating say some 1 gb memory. Also say my system has 1 gb of ram.
main()
{
malloc(1gb)
return(0)
}
The program above exits without freeing the memory.
In this case will the 1 gb of heap memory be returned... (9 Replies)

Hey All,
Quick question...
I'm writing a short script to check if a continuous port is running on a server.
I'm using "ps -ef | grep -v grep | grep processName" and I was wondering if it was better/more reliable to just check the
return code from the command or if its better to pipe to... (12 Replies)
I installed NetBSD 6.1.2 amd64 and can't find the apm utility. Is it not in the base system?
Is it necessary to recompile the default amd64 kernel to use apm?
Or is there a new method for power management and suspend/resume? (2 Replies)
Hi,
I am learning shell scripting for the first time. I use AT&T Korn Shell, Version AJM 93u+ 2012-08-01, compiled from source on NetBSD.
So far I have managed to set up what I think is a useful and pleasing shell prompt, which can be seen in the image attached to this post.
The prompt is... (2 Replies)

Usually when I on the evening go to bed I take some interesting book with me. I read it for a while to get me down to sleep. Probably most people seek information from the Nett by googleing but I am so oldfashioned I prefer a real book ;)
