My sparc2 is really sensitive to floppy quality. I tried Maxell MF2HD without
success but have had no problem using Memorex 2SHD !
(with the former medium I get read error in block 65)
However, I'm still experimenting another problem: it cannot load (or mount)
the ramdisk from the root floppy. I get the following messages on screen and
the system if stuck here:
RAMDISK: Compressed image found at block 0
EXT2-fs warning: checktime reached, running e2fsck is recommended
VFS: Mounted root (ext2 filesystem).
Freeing unused kernel memory: 40k code, 4k data
I guess the ext2fs warning is coming from my hard disk where I installed a
previous system. Therefore it seems it doesn't mount the ramdisk at all :-(
I also tried to tftpboot with no more success: still cannot mount the ramdisk.
It seems there is a problem in the root.bin image. I did a trial with the
latest released root image (2.1.6-990202): works like a charm.
Because of this problem, I will not upload new bootdisks before the end of the
week. I'll try to investigate and hope to be ready to upload them next monday
