Brandon @ Netgear wrote back to me on 7/17/2005
to say that the
Netgear
FVS124G is
not rack
mountable, throughput will be 12.5 Mbps without VPN use,
and the internal Gigabit switch does not support Jumbo
Frames. |

support SAF-TE & is the manufacturer is headquartered in
England |
Matsushita (Panasonic) never releases updated
firmware for their optical drives, their onboard firmware
also explicitly disallows regional code bypassing

A, B, C, D, & E are the pricing
"levels". A
starts at around $900.00 PowerFile C200E is a level

Connection: USB 2.0
Power Requirements: 100-240VAC 50/60Hz,
External Adapter
Warranty: One year
Removable USB cable
Arm duty cycle is unknown
What backup software can be used, how
does it span backups across more than one piece of
media? Can it write unchanged files to media, while
preserving directory structures? What is the restore
process like? QQboxx may
support data backup to the Duplix. Acronova may have
written QQboxx |
- Asetek 12V Pump/Reservoir
physical dimensions: 4.803" x 1.968" x 6.102" (Height by
Width by Length). WaterChill Xtreme [12V] Base Pump
Unit includes 1/2" OD connectors and grey parts; part number
03-L-1254 [1/2" OD fittings]. LCD Display Black
part number 03-L-1270. Asetek WaterChill "Xtreme
edition" Pump/Reservoir supports controlling two separate

- Non-conductive coolants
Integrity
PC Fluid XP+ has temperature delta of
1° C - 2° C worse than DI H2O, shelf life of 5 years, and active life of 2 years.
[Froogle]
VoyeurMods
PC
ICE has
temperature delta of 2° C - 4° C worse than DI H2O, shelf life of 3 years, and active life
of 2 years. It also has exhibited formulation
problems - some batches had dye sediment in them, it is
more vulnerable to contamination than Fluid XP, and was
initially marketed with false information - the
manufacturer outright lied about its non-conductivity and
cooling properties. |
| - The Aspire X-QPACK-AL/420's
power supply, while labelled as being 420 watts, is actually
considerably lower than 420 watts. Expect to replace
it with a different power supply. If a standard size
ATX power supply is installed in the case, a standard-length
optical drive can not fit in the top 5¼" bay.
Lite-On's shorter length optical drives will fit according
to a few people. N.B. Lite-On unit quality is
terrible. Use a laptop drive in a 5 ¼" adapter bay
instead. |
- Tripp Lite PowerAlert
software does not properly share the USB connection with
Window's APM. After about 2 days, the UPS' battery
status can not be read by either the PowerAlert software or
Window's APM. An uninstall/reinstall of the UPS
software is required to fix this error condition; rebooting
does not resolve the problem.

- Research the MSI Geminium-GO
upgradeable graphics card.
An updated
version
of the card was displayed at Computex 2006 on 6/8/2006.
The length of the card was shortened by
placing one MXM slot on the back of the PCB.
Per glossy materials: "Performance is directly
dependent on the video chip modules installed onto the
board." and
"Power
use and fan noise are diminished when compared to
dedicated "desktop" video cards when the same video
chipset."
The
board, in its current state, may be too long to physically
fit inside of a Micro-ATX case.
MSI has a reputation for demonstrating
products that will never be sold to customers. |
- Linksys 24 port smart
switches have serious reliability problems. Since
Cisco now controls Linksys, they are probably making them
build rejects

MCP78S: GeForce

MCP78H: nForce
730a motherboard chipset - By itself, it does not have an
onboard video interface

IP Cop has a built-in
DHCP server that can serve:
1) static IP addresses based
upon the MAC of the client
2) a boot image via DHCP
3) It does not have built-in
support for an LCD status display, but a third party Linux
plugin named LCDProc

models
I will need to update the 'CFontzPacket_output()' function
in CFontzPacket.c to add side LED intensity control.
Binary-only (ON/OFF) control of the Red & Green LEDs is
already supported via an 8-bit integer
First
4 LOW bits are the green LEDs, and the last 4 HIGH bits are
the red LEDs
E.G.
0x1016 = 000100002
LED 0 Red
E.G.
0x0116 = 000000012 LED 0
Green
E.G.
0x2216 = 001000102 LED 1
Yellow
E.G.
0xDD16 = 110111012 LED 0 Yellow LED 1
Unlit LED 2 Yellow
LED 3 Yellow
Page 39 in the manual describes how to modify PWM intensity
for the LEDs
Notes: LED Hardware uses a 100 Hz PWM signal to control LED
intensity.
I will use 3 bits to set intensity. 000: Off - 0% (0x0)
001: 14%
lit (0xE)
010: 28%
lit (0x1C)
011: 43% lit (0x2B)
100: 57%
lit (0x39)
101: 71%
lit (0x47)
110: 86% lit (0x56)
111: On - 100%
(0x64)
A
24-bit wide bitfield to control all 4 LEDs would work best;
6
bits per LED - the low bits control green intensity and the
high bits select red intensity
It
will convert Integer data to the bitfield
E.G.
1677721510 = 2 ^ 24 - 110 = 1111111111111111111111112
= 0xFFFFFF16: All 4
LEDs lit Yellow
E.G.
0: All LEDs off
Prefix
the data, using either a Decimal (base 10) or a Hexidecimal
(base 16) number, with an negative sign ( - ) to indicate
the alternate output format?

will silently substitute similar products when connected to
from Google Product Search, if the original item is out of

This caused me to purchase 3-pin instead
