When I did "modprobe aha1542" under Linux 2.1.103 on my PC, it locked up: flogging the keyboard had no effect and gpm (X was not running) stopped responding. Doing the same under 2.1.102 was successful:
Configuring Adaptec (SCSI-ID 7) at IO:334, IRQ 10, DMA priority 6 scsi1 : Adaptec 1542 scsi : 1 host.

Here are the first few bytes from the hard drive:

Under 2.1.102, I was able to do "mount -t ufs -o ro /dev/sda /mnt" and read the files from the drive. I got an error while doing "strings `find etc -type f`":
ufs_read_inode: zero gen ino 50066 pblk 215202 dev 8/0
but maybe that was because the NeXT hadn't been shut down properly. I was able to read the contents of the disk to an image file with no problems under 2.1.102.
My hardware: Amptron PM7400 motherboard (http://users.deltanet.com/users/amptron/7400-1.html), stepping 12 Pentium "classic", two IDE hard drives using PIO (because of a problem I reported earlier), Adaptec AHA542CF with the DIP switches set to up-down-up-up-down-down-down-up (BIOS enabled, IRQ 10, 0x334), with the Maxtor drive on one end of the bus (at boot time, I got a message similar to "start unit command failed") and Sony CDROM drive with no power at the other end, uninitialized Creative Labs Sound Blaster 32 PnP, Cirrus Logic ISA video card, floppy, serial mouse, keyboard, Realtek 8029 Ethernet card at 0x6000 and IRQ 11.
My configuration files are available at http://jpj.net/~trevor/linux/config-2.1.102-topside and http://jpj.net/~trevor/linux/config-2.1.103-topside . ___ Trevor Johnson
