While DL140 G3 is quite a new piece of hardware, RHEL4, even with the later updates, is rather old. When you decide to install RHEL4 on a DL140 G3 server, my first recommendation is this: if you decide to use the embedded SATA-II RAID controller – don’t. This is a driver-based RAID, much like the…
We all know this, right? In my new system, I have forgotten to activate the DVD-R’s DMA. I tried burning a DVD, and it went slow – real slow. I have checked the DMA status: $ hdparm /dev/hda /dev/hda: IO_support = 0 (default 16-bit) unmaskirq = 1 (on) using_dma = 0 (off) keepsettings = 0…
I had a rough experience upgrading Edgy to Feisy. Hardware listing, for generations to come: Motherboard Abit IB9, including on-board IDE controller IT8211 with firmware 1.3.1.67 and no BIOS upgrade in the near future. Nvidia 7700 with 256MB RAM on PCIe Problems: 1. With IDE controller enabled in BIOS system hangs during startup. This is…
Boel initrd files are actually compressed cramfs files. This is a menuscript for authoring and modifying these files, if needed. Assume the file in question is /tftpboot/install-initrd-i386.img: cp /tftpboot/install-initrd-i386.img /tmp/ cd /tmp/ gzip -S .img -d install-initrd-i386.img mount -o loop install-initrd-i386 /mnt mkdir initrd cd /mnt/ tar cf – . | (cd /tmp/initrd/ ; tar…
Kickstart is a great method of hands-free installation of RHEL/Centos (and other derived systems). Its power is in its easy interface and rather powerful %post scripting directives. Its weakness is in its lack of flexibility where it comes to package selection and various custom actions. On some cases, companies use web interface (usually home-made) which…
Unlike the expected header, this is not about silently routing packets between interfaces, or bridging multiple networks. This is all about how ants, which find the summer the best time to start investigating our place, can show innovativeness, and can prove that even ants can use network bridges, when required. The cable was in-air, not…
