333e99113b IBM ESDI MCA, 8514/A, XGA and Rancho changes: 
ESDI MCA: Increased esdi_time from 200 to 512, should fix the timeout that caused the bad attention 03 fatal.
Rancho: Added the Rancho RT1000B-MC MCA SCSI controller, it uses the 8.20R BIOS.
8514/A: Reworked the Outline command to satisfy the manual and the win2.10 (286/386) driver.
XGA: Initial rom len is set to 0x8000 (which, after being configured, is set back to 0x2000) just to not make it hang with POST code 40 25 on most configurations.
