... old battery. F12 to access the bios on power on. Porting OpenBSD ...

friday, 3 october 2025
Dell BIOS update Used rufus to create a FreeDOS usb pendrive, then rebooted the Latitude 7290, using F12 to get to boot options, I had tried F1 but it's F2 on the 7290. From the F12 boot options menu there was a BIOS Flash Update option which found the update exe file on the usb pen drive. The BIOS upgrade went smoothly and the 7290 is now running "1.42.0" from the previous "1.33.0". 2600: The Gamer Club 153 Bath Lane

Latitude 7290 & 7280 Installing OpenBSD on old Dell Latitude 7290 and 7280 was pretty straight forward. Needed hints from OpenBSD UEFI bootloader to get OpenBSD installed, also needed to play with the Dell BIOS to set it to legacy mode to install and then set it back to UEFI to boot. doas /sbin/newfs_msdos sd1i doas mount /dev/sd1i /mnt2 doas mkdir -p /mnt2/efi/boot doas cp /usr/mdec/BOOTX64.EFI /mnt2/efi/boot According to Wikipedia the 7290 is a 2018 model (went out of support in 2022) and the 7280 is a 2017 model.

Soekris Net4501 Garbage on console until I remember that the baud was 19200. Upagrade comBios to 1.33 using cu ~X and the comBios download command, oh and upgraded the Net4501 to OpenBSD 6.0. But forgot to create boot.conf: stty com0 19200 set tty com0 luckily it works from the boot prompt. Black History Month 7 Pioneers in ComputerScience Ursula K.

Lenovo IdeaPad S10-3 My IdeaPad was not letting me get into the BIOS, and the ethernet stopped working - this was resolved by dismantling and removing the CMOS battery from the motherboard, causing the BIOS to be reset. Lenovo S10-3 Disassembly Guide was really helpful. Also noticed that the built in athn0 is now working, as can be seen in the dmesg :~) ssh Confusion between -L connections on the local (client) host or -R connections on the remote (server) host: -L [bind_address:]port:host:hostport and -R [bind_address:]port:host:hostport partly due to the fact that I was already using a ssh tunnel to connect to the machine from which I was trying to forward a connection from the remote side. ssh -vvv -R port:host:hostport my.server Pre-Reg

Portege R830-13C Bought a refurbished Toshiba Portege R830-13C laptop, on first boot I pressed F2 and set the BIOS to boot from CD, I then put in my OpenBSD 5.3 CD, and installed OpenBSD 5.3. I then downloaded and installed OpenBSD 5.4-beta. The plan is to have this laptop dual booting between OpenBSD and Debian. Installed debian in the first partition of the disk. Getting GRUB to play ball was a nightmare - the documentation did not mention the solution: menuentry 'OpenBSD' { set root=(hd0,openbsd1) chainloader +1 boot } This needs to go in the 40_cutom file,then run: update-grub to update the appropriate grub files.
