In slackware12.1, when update the current ATI driver 8.42 to the latest 8.6. I can use the finger-ring on mice now. By the way, after run ATI install scripts, it also should run “aticonfig” to init some parameters. Till now,the screen mess does not happen again.

HDD lost issue was found at May 5th, as Liu Changjing verified the units sent to customer. Later, we tried almost all LSI firmware including original 6.0.1, 8.0.1-0035/38, and even the latest 9.0. While all this versions have various problems: HDD lost during fast initializing and slow initializing, and 9.0 can not recognize attached JBOD device at all. After contact with manufactory, and decided to upgrade from current backplane firmware 2.92 to 2.94, tuning the i-Button parameter(Post Delay =2). Till not, neither of above can resolve this issue as it seems we did not find the root cause.

Shanghai, an important customer need high-performance equipment, including Quad-Core, and 16GB Fully Buffer DIMM, it will encountered unexpected shutdown when load very heavy. Now, we find it is caused by no sufficient power supply. A solution is change the fan boards cables to motherboard, which is now shared from the backplane and harddisk.

I’m very tired during these days, and I know I can not lose confidence by myself: Life is going on, I must fight with my fate.

Fix firefox crash in Slackware 12.1
Error messages:
# firefox
/usr/lib/firefox-2.0.0.14/run-mozilla.sh: line 131: 3048 Segmentation fault “$prog” ${1+”$@”}

Resolution:
This issue is caused by “scim”.
# chmod +x /etc/profile.d/scim.sh
# chmod +x /etc/profile.d/scim.csh

And add a new script “scim_start.sh” to “~/.kde/Autostart” directory:
# cat scim_start.sh
scim -d
It means autostart scim after X start.

Now, firefox return.

Yesterday installed Slackware 12.0 on dell Optiplex 320, and find its default video driver “VESA” only support “1024×768 61Hz”. So download the latest ATI Linux driver “ati_driver-installer-8.443.1-x86.x86_64.zip”, execute unzip and run the codes in text mode, it would display a command line gui for step-by-step configuration and setup. Follow the way, final can see the LCD has already support “1280×1024 75Hz”. It’s very cool and has nice gui of my slackware, even more beautiful than former Mandriva.

Do you know that the harder thing to do and the right thing to do are usually the same thing? Nothing that has meaning is easy. “Easy” doesn’t enter into grown-up life.

I remember once imagining what my life would be like, what I’d be like. I pictured having all these qualities, strong positive qualities that people could pick up on from across the room. But as time passed, few ever became any qualities that I actually had. And all the possibilities I faced and the sorts of people I could be, all of them got reduced every year to fewer and fewer. Until finally they got reduced to one, to who I am. And that’s who I am.

Pang will go to Taiwan tomorrow, just for changing password and re-configure PVG.

According to communication with Poweron TE, I know their requirements clearly and later created a report to Gavin. Poweron needs serial port to control Keyboard, which this port is used for debugging on current BX1200 system. I am going to build the testing environment and find the solution.

WebDisk and PVG would be integrated into a whole system, Pang said this is for convenience to carry the devices to Singapore(Demo Show). It seems Huang Pengcheng has became working on this issue.

Shan, Xiaoyu will arrive at Shenzhen, and he will give a training to Product Departments and Customer Service Team in Shenzhen. He is a good fellow.

FAQ and Feedback form, I will write these two documents in recent days.

Last Sunday, I went to Zhuhai with my wife. Zhuhai is still a quiet city, gray sea, blue sky and hot sunshine. It’s very nice to meet Plasmon’s old friends, Sam, Kevin, and Hans. Hans has been living with his girlfriend, who was working in Guangzhou when I am in Plasmon. Kevin said he plan to leave Plasmon and look for a revive. Sam now lived in 4rd floor, he even brought a game joystick for car racing. Everything looks so familiar, just as happened in yesterday, while it has been about one year. Thank you, my friends. It’s you who make me have the above feeling.

BIOS is shorter of Basic Input/Output System, which is stored in ROM/EEPROM/EPROM/Flash. It is a coded program, and uses a dedicated memory called CMOS to keep its implements and setting, for example, date, harddisk driver and so on. It’s a fucking life, while everyone has to live. It’s hard life.

New Super servers and workstations based on the Intel 5100 chipset, with regular DDR2 memory instead of FBD memory, offer superior performance-per-watt and cost-to-performance ratios, because DDR2 memory costs about $10 less per module compared to FBD and generate less heat.

Designed for cost-effective 1U/2U/4U and tower systems, the new X7DCL-i server board supports up to 32GB of DDR2 memory, six expansion slots including three high-performance PCI-Express slots, and six SATA2 ports with RAID5 in a standard ATX form factor. For onboard SAS support, SuperMicro also offer the X7DCL-3, which supports SuperMicro also offer the X7DCL-3, which supports eight SAS ports with RAID5 optional.

VMDq: Virtual Machine Device Queues is another breakthrough technology from Intel that helps offload network I/O data, processing from the VM monitor software to network silicon.

Receiving Packets: As data packets arrive at the network adapter, a layer 2 classifier/sorter in the network control sorts and determines which VM each packet is destined for based on MAC addresses and VLAN tags, then places the packet in a receive queue assigned to that VM. The hypervisor’s switch merely routes the packets to the respective VM instead of performing the heavy lifting work of sort data, Thus, VMDq, improves platform efficient for handle receives side network I/O and increase CPU utilization for application processing.

EIDE: Enhanced IDE, the latest ATA version is 8, which is also in processing.

48bit address, equals 144 PeraBytes.

LSI 1068E chipset, by setting a jumper, can be used in 2 modes.

1. 1068MPT-Fusion, PCI ID 1000:0054, Embedded MPT-Fusion BIOS, used with MPT-Fusion(SAS) driver.

2. 1068MegaRAID, PCI ID: 1000:0055, Embedded MegaRAID BIOS, providing RAID 0,1

LSI MegaRAID 84016 SAS controller contains two 1068E controllers and one Intel ICP unit. It driver is megaraid_sas.ko, not mpt_sas.ko as 1068E D.Card in BX1200 platform, which just acts as HBA card.
