How come FreeBSD does not detect my HP Netserver's SCSI controller?

Frequently Asked Questions for FreeBSD 2.X, 3.X and 4.X
This is basically a known problem. The EISA on-board SCSI controller in the HP Netserver machines occupies EISA slot number 11, so all the ''true'' EISA slots are in front of it. Alas, the address space for EISA slots >= 10 collides with the address space assigned to PCI, and FreeBSD's auto-configuration currently cannot handle this situation very well. So now, the best you can do is to pretend there is no address range clash :), by bumping the kernel option EISA_SLOTS to a value of 12.

Why does FreeBSD not recognize my Adaptec SCSI controller card?

Frequently Asked Questions for FreeBSD 2.X, 3.X and 4.X
The newer AIC789x series Adaptec chips are supported under the CAM SCSI framework which made it's debut in 3.0. Patches against 2.2-STABLE are in ftp://ftp.FreeBSD.org/pub/FreeBSD/development/cam/. A CAM-enhanced boot floppy is available at http://people.FreeBSD.org/~abial/cam-boot/. In both cases read the README before beginning.

How come FreeBSD does not recognize my Bustek 742a EISA SCSI controller?

Frequently Asked Questions for FreeBSD 2.X, 3.X and 4.X
There are 2 general ''versions'' of the 742a card. They are hardware revisions A-G, and revisions H - onwards. The revision letter is located after the Assembly number on the edge of the card. The 742a has 2 ROM chips on it, one is the BIOS chip and the other is the Firmware chip. FreeBSD does not care what version of BIOS chip you have but it does care about what version of firmware chip. Buslogic will send upgrade ROMS out if you call their tech support dept.

What does it mean when the SCSI Detect light on the T4 SCSI bridge is blinking?

Tableau Frequently Asked Questions
After the T4 SCSI bridge is turned ON, it begins scanning the SCSI bus searching for a device. If the SCSI device is ready for operation, the T4 turns ON the SCSI Detect light. If the SCSI device is not ready, the T4 flashes the SCSI Detect LED until the SCSI device reports that it is ready for operation. If the SCSI Detect LED never stops flashing that most likely means the SCSI device is malfunctioning.

ServoMaster doesn't detect my USB controller, why?

ServoMaster: Frequently Asked Questions
The following output from servomaster_console would be a good indication that you're having this problem: Unable to initialize controller, cause: java.io.IOException: No compatible devices found. Make sure you have /proc/bus/usb read/write permissions. at org.freehold.servomaster.device.impl.usb.AbstractUsbServoController.findUSB(AbstractUsbServoController.java:259) at org.freehold.servomaster.device.impl.usb.AbstractUsbServoController.doInit(AbstractUsbServoController.java:474) at org.freehold.

What is FreeBSD?

Frequently Asked Questions for FreeBSD 2.X, 3.X, 4.X and 5.X
Briefly, FreeBSD is a UNIX® like operating system for the i386™, IA-64, PC-98, Alpha/AXP, and UltraSPARC® platforms based on U.C. Berkeley's ''4.4BSD-Lite'' release, with some ''4.4BSD-Lite2'' enhancements. It is also based indirectly on William Jolitz's port of U.C. Berkeley's ''Net/2'' to the i386, known as ''386BSD'', though very little of the 386BSD code remains. A fuller description of what FreeBSD is and how it can work for you may be found on the FreeBSD home page.

How do I disable the SCSI controller?

Iomega Buz FAQ
If you don't have any SCSI devices attached to your Buz, or you don't use them from DOS, there is no reason to put up with the long "Iomega Jet SCSI" BIOS sequence. This is where the machine probes the Buz SCSI bus for devices at boot time, before Windows starts. To disable this boot-time probe, remove the EPROM on the Buz! The 64k EPROM on the card contains the BIOS boot code for the SCSI controller. If you don't have SCSI devices, you don't need it.

Can I use my 4020i with a SCSI controller other than the Advansys controller it ships with?

HP SureStore 4020i FAQ
Yes you can. I have successfully used the 4020i with an Adaptec 1542CF controller. The only change that I had to make was in the SCSISelect utility. Upon getting into SCSI select, you will need to select Device Configuration. Then go to the ID that the 4020i is on (default = 2). Where it says YES for FAST SCSI, change it to say NO. If you attempt to burn CDs when this is set to YES, you will run into mysterious Buffer Underrun Errors. I don't know why this causes buffer underruns, but it do...

just how many positions the Intellivision controller can detect?

Intellivision World :: Official Intellivision FAQ 7.0
Yes, it is 16 positions! This control disc was "revolutionary" for its time, allowing for greater control with sports titles, but is also one of the reasons Intellivision never did catch up to the Atari 2600.

What other devices does FreeBSD support?

Frequently Asked Questions for FreeBSD 2.X, 3.X and 4.X
FreeBSD supports APM on certain machines. Please look in the LINT kernel config file, searching for the APM keyword. Further information can be found in apm(4).

Can I plug the Buz into my existing SCSI controller?

Iomega Buz FAQ
This is included here because it's a Frequently Asked Question, but... it's completely nonsensical. The Buz is a SCSI controller, not a SCSI target device (like a tape drive or hard disk). If you're asking this question, you probably have a misunderstanding of how the Buz device looks and works. And now, for the technical nit-picking..

What does it detect?

Heart & Vascular Institute: Frequently Asked Questions About...
The scan will detect the volume and density of coronary calcium deposits in the patient's coronary arteries.

If a Malakite resonates a person controlled by a Shedite, who does he detect?

In Nomine Frequently Asked Questions - Celestials
Generally, the controlling personality, which is the Shedite. On a particularly good roll with a particularly good check digit - or a Divine Intervention - the GM may want to give results for both the host and the demon.

How does ThunderBolt detect lightning?

Frequently Asked Questions
Lightning is the flow of huge amounts of electrical current within a storm. These currents can range from several thousand amps, all the way up to 250,000 amps. (For comparison, a typical household circuit carries 10-20 amps of current.) The ThunderBolt has a high sensitivity receiver/amplifier that captures a specific frequency in the electromagnetic noise produced by these huge flows of electric current.
