-
- Recently I had a chance to install minix-1.5 on Gateway-2000/486dx2/50MHz,
- and met troubles on FDD.
-
-
- At first, I've tried to boot-up AT-boot from 3.5'-FDD, but after showing
- menu, and responding my "="-pressing, the machine fell into sleep, light
- on FDD in keeping ON.
-
-
- Next, I've tried to boot-up minix-DEMO-disk, but it was the same, at first
- BIOS-FDD works well, but FDDriver on Minix does not work, even 3.5"-FDD is
- quite well under MS-DOS.
-
-
- Fortunately, booting from 5'-FDD could, in my case, so I could install
- minix through 5'-FDD.
-
-
- Thus, I saw source-codes of kernel/floppy.c, there such codes have been
- found;
- ------------------------------------------------
- const MAX_FDC_RETRY = 100;
- |
- retries := MAX_FDC_RETRY;
- while not ready do begin
- DEC(retries);
- if retries <= 0 then exit(IOerror);
- end;
- fdc_out(port,val);
- exit(NOerror);
- ------------------------------------------------
-
- I thought waiting-time is too short for 486-machines, thus increased the
- contents of MAX_FDC_RETRY upto 1000, then all the works can be done suc-
- cesfully.
-
- After that, I asked my net-friends in case of Linux and 386bsd, the former
- uses 10000, and the latter 100000 for the waiting count. So, I think
- "100" is too small in case of 486-machines.
