I'm trying to install OS 7.5.3 on a new disk file, and I'm booting into 7.0.1 from the bootup disk provided with the guide here: http://www.emaculation.com/doku.php/basilisk_ii_setup
However, when I do, I receive a checksum error when I try to extract part 1 of 19 to create the install volume. Basilisk loads "fine", that is I can get it to the desktop without too much issue. I'm running the latest build, and I have it set to Mac IIci (MacOS 7.x), 68040 processor, and I'm using a 1M Performa 630 ROM.
I have tried copies of the system 7 software from 2 different locations, as well as trashing the .hfv file I had and creating a new one. I have used the hfv explorer to copy the files correctly.
The installer verifies the first stage, but it stops with a failed checksum check after verifying the 19 parts.
Any ideas are welcome, thanks!
