- Hello Julian and all netter,
- I appreciate your folloing post.
-
- >>The problem is that the aha1742 does not correctly emulate 1542
- >>intructions 3 and 4 (used in the 'as' driver)
-
- I am feeling I should read the technical documentations of the adapter.
-
- >>the new disks are using the NEW scsi drivers.
- >>the devices are called sd0[abcdefgh]
- >>rather than as0[abcdefgh], though as0 and sd0 are the same device
-
- Oh! I didn't know this. Anyway, by using /dev/as0? devices, I have got
- my HD + the adapter worked. Thanks. I'll make /dev/sd0?.
-
- I report my New mistake this time,
- Even I have finished to install 386bsd once, I had a trouble again.
-
- After an installation, I re-formatted my HD by DOS/fdisk to change
- the disklabel. Since this re-formatting, I couldn't put a disklabel
- to the HD again. The disktab entry was something wrong.
-
- Finally I have found the reason.
- My disktab entry reflected the HD's physical geometry first.
- However, an aha1742a adapter has the track number translation
- to avoid DOS 1024 track limitation.
-
- After the re-formatting, the HD's partition table was modified
- by a logical geometry table (63 heads, 32 sectors/track).
- Because of this, I had to generate a new disktab entry which
- reflect the logical(=translated) geometry.
-
- This is my careless mistake, but probably someone may have similar
- troubles. Be carefull, new 1740 users.
