To boot an hdd installation with no need for usb device, you must copy kloader2.1.elf to the memory card along with vmlinux_fat_and_slim_v4.gz which together are less than 2.4MB (use ULaunchELF to copy). Note that this is still a significant size for an 8MB card so you might want to use a memory card in the second memory slot to hold these files. They will load off of a 128MB card, but much slower. You must then start kloader2.1.elf and press any key on the gamepad or keyboard to stop the autoboot of PS2-Linux. Then use the kernel selection menu to select vmlinux_fat_and_slim_v4.gz and then use the File menu to save the settings after doing this. You can then run kloader2.1.elf from the memory card (put in the ULaunchELF menu) and it will auto-start PS2-Linux from your hdd.
I borrowed the usb drive I'm using how do I boot linux with out it?
I don't have an HDTV but I assume you are at first wanting to try an xmode setting of NTSC,nointer or PAL,nointer which should put you at 448 or 576 lines instead of 240, and it should be compatible with your AV1. If you have the RTE SBIOS you can use DTV settings. Please refer to the end of the file ps2linux-installer_v0.8.txt in the ps2linux_v0.8.zip file for more settings. You can change xmode in /ps2linux/install_config/ps2linux.cfg on your usb drive and rerun the installer with radshell.elf, selecting "c" for reconfiguring settings on your hdd installation (without having to do the whole install over). You probably want to try fixing the video before doing the above part setting up to start from the memory card.

Very cool. I got my start in the same era with a TRS-80 Model 1.
I have not used line commands since my early days (Comadore 64) back in the late '70s.
